5 Sure Shot Reasons Behind That Acidity

5 Sure Shot Reasons Behind That Acidity

Acidity or acid efflux refers to a sharp pain and burning sensation in the center of a person’s chest. Often referred to as heartburn, this disorder affects millions of people across the world. Even though suffering from acidity once in a while is more or less normal, a frequent case of acid reflux may be indicative of a more severe underlying condition.

Here is a look at some of the common reasons behind your recurring acidity.

  1. Lying down after a meal: A meal requires a bit of time to get digested. Before digestion, the acid is contained in the stomach using the diaphragm. However, if you lie down right after having a meal, the diaphragm may or the lower esophageal sphincter (LES) may open up, causing the stomach acid to spill into the chest. This can alleviate acidity symptoms. Similarly, a particularly heavy meal can also cause acidity.
  2. Obesity: People who are overweight or obese have a greater risk of suffering from acidity compared to those who maintain an ideal body weight. So, start exercising and losing the extra pounds if you have been suffering from acid reflux for quite a while now.
  3. Certain foods: Citrus fruits and vegetables contain citric acid, which help in increasing the overall acidic level in the stomach. Other foods, which should be avoided and can be a cause for acidity include chocolates, garlic, mint, onions, oily and fatty foods. You do not have to stop having these foods completely, but you should try to avoid them as much as possible.
  4. Certain beverages: Alcohol consumption can often lead to acidity. It is best to avoid regular alcohol consumption and even if you choose to have a peg or two, make sure it is only for a limited period of time. Regular or excessive consumption of other artificially sweetened drinks, carbonated drinks and even tea or coffee, can also lead to acid reflux syndrome. If you partake any of these drinks, try to reduce the amount and ingest as little as possible.
  5. Pregnancy: Pregnant women undergo a plethora of changes in their bodies. Some are visible from the exterior, while the others happen inside the body. A range of hormonal changes occur at this point in time which can cause certain problems in the body. One of the major hormones linked to acid reflux during pregnancy is progesterone. This hormone is vital for the proper growth and development of the fetus, but the hormone also slows down the rate of digestion.

GERD - Complications That Can Possibly Lead To It!

GERD - Complications That Can Possibly Lead To It!

GERD or Gastroesophageal Reflux Disease is a condition in which the stomach acids spill back into the esophagus due to a malfunctioning diaphragm muscle just above the stomach sac. People suffering from such a condition are likely to experience heartburn almost every time they have a meal.

However, not everyone who suffers from heartburn necessarily suffers from GERD. In fact, occasional heartburn is quite common and does not indicate any underlying condition. However, if the frequency of heartburn increase, you should probably get yourself checked by a gastroenterologist. Apart from the burning sensation in your chest, you may also experience a sourness at the back of your throat.

Here is a look at some of the leading complications in the body that can lead to GERD.

  1. ObesityObese people are at a greater risk of suffering from the Gastroesophageal Reflux Disease. This is because the fat deposited in and around the stomach region in obese individuals can sometimes lead to the lower esophageal sphincter or LES, the muscle flap that separates the stomach from the esophagus, to loosen. This leads to the stomach contents spilling back up the esophagus.
  2. StressEven though stress does not directly lead to GERD, it may act as a catalyst for the symptoms of the disease. Studies have revealed that people who are stressed out are at a greater risk of complaining about GERD symptoms than people who are in a relatively relaxed state of mind. Doctors call this condition ‘hypervigilance’, where even a little discomfort may seem like an extreme pain.
  3. Hiatal hernia: This is a condition where the stomach itself pushes against the LES muscle, causing it to open. A hiatal hernia is an underlying condition and in such a case, immediate treatment is necessary to eradicate the GERD symptoms completely.
  4. PregnancyPregnant women undergo several hormonal changes in their bodies. Some of these changes may have an adverse effect on the body of the mother but are necessary for the overall growth of the fetus. One of these hormones is progesterone whose concentration in the blood increases drastically during pregnancy. This can sometimes lead to the mother developing GERD symptoms. However, the condition should be treated once the baby is delivered and the mother’s hormone levels come back to their normal levels.

At any rate, people suffering from GERD should consult a gastroenterologist and avoid smoking, drinking alcohol. In case you have a concern or query you can always consult an expert & get answers to your questions!

5 Common Stomach Disorders!

5 Common Stomach Disorders!

A healthy digestive system is a boon for any person, but very few people in the world have immaculate digestion. Disorders related to digestion can create serious issues, which may, in the future, lead to severe and chronic diseases. Here is a look at some of the most common stomach disorders that may plague you or someone you know.

  1. Gastroesophageal Reflux Disease (GERD): Many a time you may have heard people complaining about acidity. This acidity is the primary symptom of GERD. People suffering from the same can experience pain and a burning sensation in the center of their chests. This usually occurs after you have just finished off a meal. Ingesting spicy food may also lead to the condition. However, it is important to remember that not all acid reflux cases are indicative of GERD. If the frequency of such acid reflux increases, it could be a pointer for GERD.
  2. GallstonesGallstones are small and hard crystalline deposits that are formed in the gallbladder. The main cause of gallstone is excess cholesterol and deposition of bile in the bladder, in case the gallbladder does not empty completely. Gallstones can cause sharp pain and need to be removed using laser surgery. Smaller stones may be passed out naturally with feces, by the help of medication, without the need for surgeries.
  3. Celiac diseaseCeliac disease is a disorder where the body’s immune system reacts violently towards gluten. Gluten is a form of protein, which is often found in bread and any product containing refined flour. People suffering from celiac disease may need to be admitted to the hospital due to an allergic reaction to gluten. There is no permanent treatment for this disorder and people, who suffer from this disease, need to stay away from gluten forever.
  4. Irritable bowel syndromeAs the name suggests, irritation in the digestive tract may be a sign of IBS. In such a case, you will feel terrible pain and discomfort. Other symptoms include constipation in some cases, while diarrhea may also be caused as a result of the disorder. If you are suffering from the disease, ensure that you stay away from dairy products, artificial sweeteners, alcohol and caffeine.
  5. Ulcerative ColitisThe large intestine is affected in this condition It is caused when your immune system mistakes food for foreign particles and rejects it. If you experience pain and diarrhea or notice blood in your stool, it could be indicative of ulcerative colitis.

Peptic Ulcers - Strange Things About It!

Peptic Ulcers - Strange Things About It!

Peptic ulcer, often referred to as stomach ulcer, is usually a misunderstood disease. Most people are unaware of the reasons why the ulcer is caused and are also unaware of the early symptoms of the disorder. Here is a look at some of the strange facts about peptic ulcers that you may not know.

  1. Stress does not cause ulcers: The myth that stress causes ulcers is just that- a myth. Ulcers are not caused by stress and tension. However, if you are already affected by an ulcer, stress can alleviate the symptoms and make matter worse. Non-steroidal anti-inflammatory drugs can result in ulcers. So, if you have already been diagnosed with peptide ulcer, try not to stress too much.
  2. Ulcer pain is not caused due to food: Contrary to popular belief, ulcer pain is not alleviated when you eat something. In fact, pain increases if your stomach remains empty for a long period of time. So, if you are an ulcer patient, make a point of eating at regular intervals. In fact, the American College of Gastroenterology claims that people with ulcers do not need to follow a bland diet in order to recover from the condition.
  3. Heartburn medication is effective against ulcer: Stomach acid is the common link between heartburn and ulcer, as both of these disorders are caused as a result of excess acid formation in the stomach. This is why physicians often prescribe antacids to ulcer patients.
  4. Untreated ulcers can be problematic: Ulcers are easy to cure and can be completely treated with proper medication and adherence to restrictions. However, you should seek treatment for ulcers as soon as it is diagnosed. If left untreated, this ulcer may go on to cause severe issues for the patient. For instance, untreated ulcers may lead to internal bleeding and scar tissue. The same also impedes the digestive process. So, do not leave ulcers untreated and think that they will be repaired automatically over time.
  5. Endoscopy is the best way to diagnose ulcers: Even though X-rays may often reveal ulcers, a normal X-ray cannot detect certain smaller ulcers. Endoscopy is the best way to detect the disorder. In this process, a small tube, containing a light and a camera, is inserted inside the patient’s esophagus. The camera reveals any abnormal growth or infection inside the stomach. If you suspect an ulcer, book an appointment with the doctor as soon as possible.

GERD - 4 Ways To Treat It!

GERD - 4 Ways To Treat It!

Gastro-oesophageal reflux disease (GERD) refers to a health condition wherein the stomach acids tend to leak backwards from your stomach into the oesophagus, causing the latter to experience a good amount of irritation, thereby triggering a number of other problems. GERD has a way of affecting people irrespective of their age or gender. Patients who suffer from asthma are at greater risks of encountering the problem of GERD, and some asthma medicines tend to worsen reflux symptoms. However, the effects are indeed two-way in this regard. Acid reflux worsens asthma symptoms by deeply affecting the lungs and airways. Allergic reactions might also be brought about as a result of such a condition.


GERD is a condition that everyone has experienced at one point or the other in their lives. It generally happens when on burping you are left with a bit of an acid taste that lingers in your mouth, followed simultaneously by a case of heartburn. A sure way to ascertain this condition is to check for the following symptoms: 

  1. Sudden and excessive rise in saliva
  2. Acid regurgitation
  3. Gums show inflammation
  4. Sore throat that is chronic
  5. Bad breath
  6. Cavities
  7. Encountering pain or difficulty while swallowing
  8. Hoarseness or laryngitis
  9. Chest pain

How can it be treated?

The prime treatment measure for GERD is to adopt necessary lifestyle changes so that you may nurture better health. In case you happen to be overweight, it is important that you look into the matter of weight loss.

  1. Medicines must be taken along with a lot of water, and doctors must ensure that prescribed medications do not actually worsen your heartburn.
  2. Over-the-counter medications and antacids can be used every once in a while after meals, but it does one good to remember that the effects don’t last for long. Side effects of excessive dosage of antacids include constipation or diarrhoea.
  3. Proton pump inhibitors might also be recommended in acute cases of GERD to reduce the total amount of acid that is manufactured in your stomach. H2 blocker is another antidote that aims at reducing the level of acid that is released in your stomach.
  4. Anti-reflux surgery is also prescribed for those people whose symptoms persist despite a change in medications and lifestyle patterns. An endoscopic surgery is another important procedure that may be opted for in order to correct GERD.

Achalasia - Can Autoimmune Disorders be the Reason Behind it?

Achalasia - Can Autoimmune Disorders be the Reason Behind it?

The tube that carries food to your stomach from your throat is called the oesophagus. When the muscular valve (lower oesophagus sphincter) in the oesophagus fails to relax and carry the food to the stomach, the condition is termed as achalasia.

Achalasia has a variety of causes, and can be difficult for your doctor to diagnose the exact cause. Some common causes of achalasia include:
1. Hereditary predispositions
2. Autoimmune disorders (The immune system erroneously destroys healthy cells in the body)
3. Nerve degeneration in the oesophagus
There other medical conditions that often lead to symptoms identical to achalasia, such as oesophageal cancer and Chagas’ disease (an infectious disease caused by a parasite).

Other symptoms of achalasia include:

The most prominent symptom of achalasia is dysphagia, which is characterised by swallowing difficulties or sensations of food stuck in the oesophagus. Dysphagia often triggers coughing and shortness of breath or choking on food.
1. Discomfort or pain in the chest
2. Weight loss
3. Heartburn
4. Intense discomfort or pain after eating

Some of the treatments include:

Most of the methods to treat achalasia focus on the lower oesophageal sphincter (LES). The treatments used can either permanently alter the sphincter’s function, or reduce symptoms.
1. Oral medications such as calcium channel blockers or nitrates are prescribed, which can relax the LES to let food pass through with more ease. Your doctor may also treat the LES with Botox.
2. For a more permanent treatment, the sphincter can be dilated or altered. In dilation, a balloon is inserted into the oesophagus and it is inflated. This will stretch out your oesophagus to improve function.
3. To alter the oesophagus, oesophagomyotomy is performed. It is a kind of surgery where minimal incisions are made to gain access to the LES, and then it is carefully altered to improve flow of food to the stomach.

Unlike dilation, which can cause complications such as tears in the oesophagus, oesophagomyotomy has a greater success rate. However, certain complications may still arise, such as:
1. Acid reflux
2. Respiratory conditions that are caused by food entering your windpipe

Gastroesphageal Reflux Disease - How Can It Be Managed?

Gastroesphageal Reflux Disease - How Can It Be Managed?

GERD or gastroesophageal reflux disease is a chronic digestive disease which occurs when the stomach acid and at times the contents in your stomach flows backwards into the food pipe. The backwash or reflux irritates the esophagus's lining and hence causes GERD. Individuals may manage GERD's discomfort by changing their lifestyle and by taking over-the-counter or OTC medications. But, certain people might also require stronger medications or surgery for reducing the symptoms.

Some of the basic signs include chest pain, burning sensation in the chest, dry cough, difficulty in swallowing, sore throat, etc. If you experience such symptoms at least twice a week or if your physician notices damage in your food pipe, then you might undergo diagnosis. Though drugs are the primary GERD treatment yet, an individual can manage it by following certain tips which may give relief.

Few ways to manage GERD- self-care tips:

  1. One of the effective ways to help yourself is by consuming smaller meals. Instead of taking three big meals regularly, you may try having smaller meals frequently and avoid stuffing.
  2. Almost all individuals tend to have dinner just half an hour before sleep, but this might affect GERD patients. It is best to eat 2 hours before going to bed as by doing so your stomach will get enough time to digest the food.
  3. Due to a hectic schedule and fast paced lifestyle, people tend to eat as quickly as possible. To manage GERD, one must eat slowly and put down the spoon or fork in between each bite.
  4. Changing the daily diet by striking off the trigger foods is beneficial in managing GERD symptoms. Though the food triggers vary from one person to another yet, it includes coffee, chocolate, peppermint, alcohol, tomato, citrus juices, onions, spicy and high- fat foods, etc.
  5. Sleeping with the head end of the bed elevated by 6 inches is a very effective way of reducing night time reflux. It is also advisable to sleep on your left side . Never sleep on the right side as this position promotes reflux. Medications to reduce acid production are the mainstay of the medical treatment.
  6. One always has to ensure that they are following the various lifestyle changes along with the medication. Other medications include pro kinetic medicines which help the stomach empty. Surgery always remains the last resort in the treatment of GERD. Endoscopy is required for the diagnosis or GERD Prior to any surgery a Manometry and 24 hr ph merry test is compulsory.

If you are suffering from GERD symptoms frequently, then you may maintain a diary for figuring out which foods are giving you trouble.

When is a surgery required?
If lifestyle changing tips and other medications fail to provide any relief, then physicians recommend undergoing surgery.

  • Surgery is done for strengthening lower esophageal sphincter and also for reinforcing it. The surgery for reinforcing lower esophageal sphincter is performed by surgeons laparoscopically. The surgeon inserts instruments like a tiny camera and flexible tube by making 3-4 incisions in the abdomen. This surgery for managing GERD may be quite effective.
  • Experts state that candidates who undergo GERD surgery are those who are unwilling to take GERD drugs or are not getting relief from them. While choosing a surgeon, it is better to consider one who possesses huge experience of the particular operation which you need and also with a good track record.
  • So, you must visit a doctor if you experience frequent gastroesophageal reflux disease symptoms. It won't be a good decision to take OTC medications without your doctor's recommendation if you notice arm or jaw pain along with difficulty in breathing as these are signs of heart attack. In case you have a concern or query you can always consult an expert & get answers to your questions!
