Gastric (stomach) cancer occurs when malignant cells form in the lining of the stomach. By far, it is known to be the second most common cause of cancer-related deaths not only in Asia but also worldwide. Though it can affect both male and female populace, it is seen more commonly in men and in people aged 50 years or older.

Type: Gastric cancers can present as one of the following types - 

Adenocarcinoma: Begins in the glandular cells lining the inside of the stomach. This forms a majority of the stomach cancers.
Lymphoma: Begins in immune system cells present in the walls of the stomach. Occurrence of lymphoma, in the stomach, is rare.
Carcinoid Tumor: Begins in hormone producing cells of the stomach.  Occurrence of carcinoid cancer, in the stomach, is rare.
Gastrointestinal Stromal Tumor (GIST): begins in nervous system cells of the stomach. Occurrence of GIST, in the stomach, is rare.
Gender: It affects both male and female populace.

Etiology: The factors that are associated with increased risk of gastric cancer include the following mostly  

 Helicobacter Pylori  bacterial infection in the stomach is a common cause of gastric cancer of both the intestinal (expanding) & diffuse (infiltrative) type. Furthermore, studies indicate that high salt intake is synergistic with H. Pylori infection in the manner that it is likely to increase the risk of gastric cancer that is induced by H. Pylori bacteria.
Smoking, consuming alcohol, red meat, salty/ smoked/ processed foods, low intake of fruits and vegetables, diets rich in nitroso compounds, eating foods contaminated with aflatoxin fungus etc all.
Atrophic gastritis characterized by chronic stomach inflammation is known to increase the risk multi-fold. Chronic gastric inflammation can lead to atrophy of the gastric mucosa, metaplasia, dysplasia and finally carcinoma.
History of pernicious anaemia, gastric ulcers, adenomatous gastric polyp etc all.
Family history of gastric cancer. Several familial syndromes that have been associated with a pre-disposition to gastric cancer include familial adenomatous polyposis, Lynch syndrome, Peutz-Jeghers syndrome and e-cadherin mutation (diffuse type)
Blood group A, Obesity etc all are known to be associated with diffuse or cardia gastric cancer.
Low socioeconomic status - persistent lifestyle issues/ irregularities including high stress coupled with an improper diet/ dietary pattern.
Epidemiological evidence is indicative of a risk or pre-disposition to gastric/ stomach cancer for people suffering from diabetes mellitus (DM).
Very high dose ionizing radiation exposure is an uncommon risk for gastric cancer.
Features: There are often no early stage symptoms. Early stage symptoms, if any, are non-specific and are likely to be ignored, thus delaying the diagnosis most often. Hence, gastric/ stomach cancer is often detected at an advanced stage where the disease is either locally advanced or metastatic. The various presentations (of signs & symptoms), by stage (early or advanced), of gastric cancer are as enumerated below:

Early Stage   can present with one or more of the following non-specific symptoms/ signs -

Dyspepsia (Indigestion),
Stomach/ Epigastric discomfort,
Bloated feeling after eating,
Mild Nausea/ Vomiting,
Blood in Vomit (Haematemesis),
Heartburn,
Weight loss (Cachexia)
Anaemia,
Occult blood in stool/ Melaena,
Advanced Stage   presents with one or more of the following symptoms/ signs -
GI Bleeding with black tarry stools (Melaena),
Persistent Nausea/ Vomiting,
Blood in Vomit (Haematemesis),
Early Satiety,
Anaemia,
Loss of Appetite (Anorexia),
Weight loss (Cachexia),
Persistent pain in the abdomen,
Fluid build-up in the peritoneal cavity (Ascites),
Edema of the lower extremities,
Liver Enlargement (Hepatomegaly)/ Jaundice,
Difficulty swallowing food (Dysphagia)
Screening: Is generally recommended for asymptomatic populations in high incidence areas or as surveillance for high risk individuals. The goal of screening, as usual, is to be able to detect & diagnose gastric cancer at an early stage which is potentially curable. It is mostly endoscopic/ radiologic.
Diagnosis: Following are the diagnostics employed in gastic cancer - 

Physical Examination: May be remarkable for palpable abdominal mass, weight loss (cachexia), abdominal distension, ascites, hepatomegaly, lower extremities edema and lymphadenopathy for gastric cancers in the advanced stage. For early gastric cancers, however, physical examination is largely uninformative.
Blood: Hb- may be low, ESR   raised, tumor markers CEA & CA-19-9 could be raised sometimes in adenocarcinoma but are not frequently elevated. Abnormal blood test results may be indicative of malignancy, but a follow-up gastroscopy/ biopsy is always the gold standard for accurate diagnosis.
Stool: Occult blood may be +ve
Barium Meal X-Ray: Could show a filling defect at the site of the carcinoma/ cancer growth.
Gastroscopy/ Biopsy: Clinches the diagnosis.
Endoscopic Ultrasound: Maximizes tumor staging as it helps determine the depth of invasion of the tumor.
CT Scan: Of chest, abdomen & pelvis helps detect metastatic disease, if any, and also helps stage the disease (TNM) appropriately.
Bone Scan: Helps detect osseous metastasis (bone mets), if any.
Treatment: Conventional treatment includes surgery, chemotherapy and radiotherapy as contextually appropriate. Surgery (i.e. gastrectomy either sub-total or total), with an adjuvant chemotherapy and/ or radiotherapy as contextually relevant, is the only treatment that is known to cure the disease in light of the prognostic indicators as briefly enumerated in the section below. Chemptherapy and/ or radiation alone cannot be curative. Mostly, it can improve symptoms, and may prolong survival. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as feasible contextually.
Prognosis: For gastric cancer is variable. Preventive measures, earlier diagnosis and right early treatment is key for an effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for an early stage gastric cancer are more. The cure/ recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all. Distal tumors are known to be cured more often than the proximal ones. Again, intestinal-type gastric cancers are known to have a better treatment outlook in comparison to the diffuse-type gastric cancers.

Prevention: Rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an adherence to a relative Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising, de-stressing and relaxation is highly recommended for reducing the risks of many cancers including gastric cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. The consumption of alcohol, if any, has to be strictly in moderation, and is best avoided in a high risk scenario. Smoking is to be avoided too. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly. Not only it is important to eat healthy, but also it is equally important to eat properly. Insufficient chewing, eating until full, eating meals within a short time etc all are best avoided so as to ease off digestive burden on the stomach/ other organs in the GI tract. Last but not the least, consumption of clean and filtered water, natural probiotics like freshly prepared yogurt/ butter milk, maintenance of cleanliness & hygiene including oral hygiene etc. all can help guard against H. Pylori infections. Breastfeeding is known to be protective against H. Pylori infections too.

Gastric Cancer - In a Nutshell!

Almost all of us have experienced bloating, gas or an upset stomach. Yet some people experience this problem at a chronic level. Gas occurs in the stomach and intestines due to breakdown of food into energy. All of us pass gas, however some people do more than others. An average person passes gas 5-20 times a day.

An upset stomach can often cause problems and can be a difficult battle for many people. Although the symptoms of gas problems often relate to an improper diet, yet other factors may be also responsible.

Causes and Symptoms of Gas Problems

Swallowing air: The swallowed air which is not burped out, passes through the digestive system and is released through the opening of the anus. Hiccups can also occur if you have swallowed excessive air.
Diet: The reaction of different foods varies from one person to another. Also foods that lead to odorous gas may also vary from person to person. Yet, spicy foods and dairy products are the most common causes of gas. Example - Beans, cabbage, onions, radishes, eggs, carbonated drinks, sugar, packaged foods etc.
Medications: Certain medicines and supplements, including prescription drugs, can lead to gas problems and bloating. Further, medications which change the hormonal balance in the body can also cause bloating.
Medical problems: Certain medical conditions such as Irritable bowel syndrome or bowel obstruction can also lead to an upset stomach.
Common symptoms of gas problems include gas pain, cramping, bloating, diarrhoea and constipation. In the worst of cases, gas and bloating indicate colon cancer. Such people experience rapid weight loss, anaemia and blood in stools.

Treatment
Modifying your lifestyle, in particular your dietary practices, is essential to a healthy recovery.

Avoiding foods such as spaghetti, oats, bran, barley, banana, bread etc. which contain high fibre content is important.
You can opt for over the counter medications after consulting your physician. Homeopathy and Ayurveda can be also opted as alternative forms of treatment.

Chronic Gas Problem - Facts You Should Know About it

Food is one of the most common ways of getting an infection, and so the stomach is more prone to infections than other body parts. Whether it is eating raw or uncooked foods or unhygienic foods, the stomach bears the brunt of one s bad food practices. The only consoling factor is that it is equally easy to treat a stomach infection if some simple measures are adhered to. 

Read on to know some of the easiest and most effective ways to treat a stomach infection.

Drink it right: What you drink and how you drink makes a lot of difference to the way your stomach infection will respond. The vomiting, diarrhoea and sweating is robbing the body of a lot of fluids, and so replenishing this fluid along with minerals is very essential. Ensure you drink a lot of clear liquids like water, coconut water, clear soups, sports drinks, and other energy drinks. Electrolyte replacement can be added to improve their efficacy. Herbal teas like ginger tea and peppermint tea are highly recommended to soothe the stomach too. At the same time, avoid caffeine, strong black tea, alcohol, and chocolate as they are detrimental to the already affected stomach.
Eat right: Even on a regular basis, you are what you eat. So, when your stomach is already infected, eating right assumes a lot more importance. Go easy on the stomach and give it something easy to digest, yet of high nutritional value. Banana, rice, apple, and toast (abbreviated as BRAT) is very easy and packs in good nutrition for the recovering stomach. Avoid a lot of fibres, fatty foods, greasy foods, sugars, and dairy products which are hard for the stomach to digest. Eat small meals, but eat a lot more frequently than you otherwise would.
Rest well: With the body losing a lot of fluids and nutrition along with it, the body would naturally feel very tired and fatigued. Let the body run its course, and give it the rest it demands. In the next couple of days, once the virus has run its course, this will resolve.
Medications: Stomach infection is usually caused by a virus, and so antibiotics do not play a curative role here. However, if you have high fever or body aches, Tylenol or acetaminophen can be used sparingly. If diarrhoea or vomiting is severe, loperamide or promethazine can also be used. However, this should be substituted with sufficient rest and nutrition (solid and liquids).
If these are not helping and you are not able to keep the food down, visit the doctor. Sometimes, a day or two in the hospital may be required for complete cure and recovery.

Stomach Infection - Easy Tips To Help You Treat It!

Diabetes is a systemic disease that affects almost every part of your body. Of these, the digestive system is the most badly affected. While gastrointestinal disorders are commonly experienced by everyone, diabetics have a much higher risk of suffering from indigestion, food poisoning, gallstones and ulcers. Some of the most common gastrointestinal problems experienced by diabetics are:

Gastroparesis: High blood sugar levels can damage the vagus nerve that controls the emptying of the stomach. As a result fo this damage, the muscles of the stomach and intestines do not work optimally leading to a condition known as Gastroparesis. This is a condition where the stomach is not able to empty itself properly and the digestion process is slowed down. Gastroparesis can cause bloating, nausea, pain in the abdomen, heart burn and a loss of appetite. It can also cause undigested food in the stomach to harden and form lumps that block food from moving into the intestines. This disease cannot be cured but can be managed with medication and a special diet.
Ulcers: Stomach ulcers can be described as open sores that develop on the inner lining of the stomach, oesophagus and beginning of the small intestine. These ulcers form as a result of bacterial infections. Diabetes weakens a person s immune system thus reducing their ability to fight these infections and increasing the risk of developing ulcers. Diabetes also increases the risk of bleeding from these ulcers and secondary infections that may arise from it.
Yeast infections: Diabetics are extremely vulnerable to yeast infections. This is aggravated by fluctuation in blood sugar levels and can extend from the mouth to the oesophagus. Common symptoms of this type of yeast infection are pain in the throat and difficulty swallowing. It may also cause heartburn and intestinal bleeding if left untreated.
Celiac sprue: This condition creates gluten allergies and causes the inflammation and thinning of the small intestine s mucosa. In some cases, this condition may interfere with the absorption of food and lead to diarrhoea and weight loss.
Diabetic diarrhoea: Patients who have been suffering from diabetes for a few years may experience an increased urge to pass stools frequently. This is usually related to gastric problems in the colon which cause fluids to move at a faster than normal speed through the small bowel and colon. It may also be caused due to the secretion of fluids in the colon and improper absorption of food.

5 Common Gastric Problems Experienced By Diabetics!!

The human digestive system is a very complicated and sizeable component of the body. It starts right at the beginning of the mouth, ending at the rectum. Some of the major responsibilities of the digestive system include absorption of essential nutrients and elimination of wastes.

Not only do digestive problems have embarrassing and unwanted symptoms, serious, chronic diseases can be caused if the minor problems are not treated.

Some digestive problems are listed below:

GERD: This is a burning sensation that results from acids in the stomach being squirted into the oesophagus. A burning sensation is felt, right from the chest to the end of the throat. Frequent heartburns can lead to GERD (Gastroesophageal Reflux Disease), symptoms of which include dry cough, sore throat, chest discomfort and difficulty in swallowing.
Bloating: This is caused due to the presence of excess gas in the colon, small intestines or the stomach.
Dyspepsia: This is an uncomfortable feeling or pain which occurs in the upper abdominal regions, mostly a result of excess food intake. It is commonly referred to as indigestion. Dyspepsia can be discomforting and if prolonged, medical assistance should be opted for.
Chronic Constipation: Persistent constipation (chronic) is a sign that there is a problem with the elimination of wastes. This usually happens when the colon is unable to move or pass stools. Other major causes of chronic constipation can be changes in your usual diet, various eating disorders, Irritable Bowel Syndrome and excessive consumption of dairy products among others.
Food Intolerance: This occurs when the digestive system is unable to tolerate certain food items. This condition is different from food allergies as it only affects the digestive system. Some of the common symptoms include diarrhoea, headache, gas and vomiting.
Possible Serious Conditions-

A gastroenterologist is a type of doctor that specializes in diagnosing and treating diseases involving the digestive system. If you continue to experience digestion problems, it s time to make an appointment.

More serious signs could mean an emergency medical problem. Those signs include:

bloody stools
continuous vomiting
severe abdominal cramps
sweating
sudden, unintentional weight loss
These symptoms could be an indication of an infection, gallstones, hepatitis, internal bleeding, or cancer.

Medications-

You may be able to overcome digestion problems with treatment and lifestyle changes. Certain diseases of the digestive system might be long-term, but medications can help alleviate symptoms.

Identifying specific digestion problems and talking with a gastroenterologist can go a long way in terms of helping your doctor give you a proper diagnosis. Remember, you don t have to put up with constant digestive issues.

Know About Digestion Problems!!

The food you eat plays an important role in your gastrointestinal health. Some foods can be difficult to digest and lead to bloating and heartburn while others increase the healthy bacteria in your gut and make digestion easier. 

Here are ten things you should include in your diet for a healthy digestive system.

1. Bananas: Bananas help regulate bowel movements and help bind food waste together thus helping with irritable bowel syndrome and diarrhea. They also help restore the electrolyte and potassium balance in the stomach.

2. Oats: Oats are rich in fiber and low in calories. It is also a rich source of phosphorus, vitamin E and Zinc. Oats helps with the proper functioning of the digestive system and the extraction of waste.

3. Curd: Curd rice is the most well known home remedy for an upset stomach. Curd is a rich source of probiotics that helps restore the balance of healthy gut bacteria and eases digestion.

4. Coconut oil: Coconut oil is an excellent substitute for normal cooking oil or butter. Coconut oil has antimicrobial properties and fatty acids that ease the digestive system and boost immunity and energy levels.

5. Lentils: Lentils are rich in prebiotics and fiber. These prebiotics promote the growth of healthy gut bacteria and prevent harmful bacteria from causing stomach infections.

6. Ginger: Herbs and spices are very helpful with digestion. Amongst these, ginger is foremost. It can be used to treat a number of stomach infections such as bloating, nausea and diarrhea. Ginger also helps 
speed up the movement of food from the stomach to the intestines.

7. Vegetables: Vegetables are rich in fiber and probiotics. While beetroots help relieve constipation, sweet potatoes help treat ulcers and bowel problems. Other vegetables that aid digestion include cucumbers, tomatoes and carrots.

8. Brown rice: A certain amount of carbohydrates are essential for a well balanced diet. Brown rice has a high calorific value but is less fattening. Brown rice helps food move smoothly through the digestive system and hence promotes regularity.

9. Peppermint: Peppermint helps ease indigestion and symptoms of irritable bowel syndrome. Peppermint can be had on its own as a flavoring agent in salads and on fruits or taken as a supplement.

10. Water: Water is crucial to healthy digestion. It helps smooth the movement of food through the digestive system and out of the bowels. Inadequate water is one of the most common causes of constipation. Ideally, you should have a minimum of 8 to 10 glasses of water a day.
