Piles or haemorrhoids are swollen veins in the rectum or anus. They can have a lot of possible causes, but the exact reason is still unknown. The one most common reason that researchers cite is the excessive straining during bowel movement and increased pressure on the veins during pregnancy. Some of the common signs of this condition include discomfort, bleeding, and itching. A clot can be witnessed occasionally. There could be swelling around the anus as well.

How is a pile diagnosed?
Doctors often recognize this condition just by doing a physical exam of the rectum. By lubricating the glove and inserting a finger into the rectum, a doctor can gauge any unusual growth around the rectum area. A doctor might also use a sigmoidoscopy or a proctoscopy to witness the lower portion of the colon. Apart from this, a doctor might prescribe a colonoscopy, if he fathoms that there is a possibility of colorectal cancer or a disease related to the digestive system.

Treatment of piles

Medication: In case of mild discomfort, a doctor might prescribe over-the-counter pads, ointments, creams or suppositories. Products such as these contain lidocaine, witch hazel or hydrocortisone that can relieve a person from itching and pain. One should stop consuming over-the-counter medicine, if there is no change in the condition.
Haemorrhoid thrombectomy: If a clot has appeared along with a pile in the rectum, a doctor can remove it by making an incision and draining the clot. This can fetch instant relief. The best time to do this is within 72 hours of clot formation.
Minimally invasive procedures: 
Rubber band litigation: This form of surgery involves placing of a couple of rubber band at the base of the piles to cut off blood circulation. In due course, the haemorrhoids fall off. Although this form of treatment works for many people, the patient has the risk of bleeding within few days of placing the rubber band.
Sclerotherapy: This form of treatment involves injecting a chemical into the haemorrhoid. The chemical shrinks the piles within few days. There is hardly any pain involved with sclerotherapy.
Surgical procedure:
Haemorrhoidectomy: This is the process by which a surgeon eradicates the excess tissue that might be causing the piles. The patient is sedated before performing this procedure. Some amount of pain is experienced after the procedure is over. The temporary difficulty of urination can be faced by a patient after this procedure.
Stapled hemorrhoidopexy: This surgery is only performed for internal haemorrhoids. The process involves blocking the blood supply. The process of stapling has less pain compared to a Haemorrhoidectomy. On the flip side, studies have shown that this procedure has an increased chance of recurrence of haemorrhoids.


Piles - Diagnosis and Treatment

Colon polyps are growths that are typically found in the large intestine. Although the causes behind the occurrence of colon polyps are not known, this condition is usually seen to affect adults.
These colon polyps might turn into colon cancer over a period of time; the development of cancer can happen over a number of years.
Colon polyps are usually symptomless; hence it becomes difficult to diagnose the condition. They are commonly found as additional results of screening tests for colon cancers. Screening tests are conducted when there is a suspicion of a disease but it displays no significant symptoms. The symptoms can only be visible if the polyps are enlarged. Typical symptoms include:
Rectal bleeding.
Changes in bowel conditions such as diarrhoea and constipation.
Changes in urination patterns.
Change in appearance of stool.
As the presence of most polyps becomes evident only during colon cancer tests, it is recommended that regular tests for colon cancer be conducted for adults over the age of 50. Some of these tests include:
Colonoscopy: This is highly recommended for detecting colon polyps. A small tube used for viewing is inserted into the colon by the doctor.
Flexible Sigmoidoscopy: It is similar to colonoscopy with the only difference being that the tube is smaller.
Computed Tomographic Colonography (CTC): Also known as virtual colonoscopy, various computer systems and X-rays are used to create a detailed picture of the colon so that the doctor can search for polyps.
The size of the colon polyps helps to identify if the polyp is cancerous or not. Chances of the polyp being cancerous are high if the size of the polyp is higher than 1 cm or 0.4 inches. Hyperplastic polyps (smaller polyps) do not become cancerous and hence, do not need to undergo a colonoscopy. Another form of polyp is the sessile polyp which is usually a flat growth without a stalk and grows on the inner wall of the colon. Similar to other polyps, these polyps can be found and removed using a colonoscopy or a sigmoidoscopy.

Causes and Symptoms of Colonic Polyps

Renal Tubular Acidosis is a medical condition. When the kidney is unable to acidify urine, it leads to the accumulation of acid in the body. Usually, when blood is filtered by the kidney, it passes through the tubules of the nephrons (the functional unit of the kidney).

Before it flows into the bladder from the kidney, the urine undergoes an exchange of salts, acids and other solutes. Renal tubular acidosis results in the formation of excessive amounts of acid because the kidneys cannot drain them. This may happen because the kidneys cannot reabsorb the alkaline bicarbonate ions from the urine in the early segment of the nephron or because of inadequate production of acidic hydrogen ions in the latter half of the nephron.

Renal Tubular Acidosis is simply associated with abnormal urinary acidification. Other functions of the kidneys remain unimpaired.
There are several different types of renal tubular acidosis-

  Distal Renal Tubular Acidosis (RTA)
This is the most fundamental form of RTA. It is characterized when the hydrogen ions are not secreted into the lumen of the nephron by the alpha-intercalated cells of the medullary collective duct of the distal nephron. When this happens the pH of urine cannot be brought down below 5.3. Renal excretion is inhibited and hydrogen ions are not eliminated which leads to academia. At the same time, Potassium ions cannot be absorbed by the cell which leads to hypokalemia. The end result is protein retention and potassium excretion. Distal RTA can lead to the urinary stone formation, calcium deposits in the kidney, rickets and osteomalacia and Sjogren s syndrome.

  Proximal RTA
When proximal tubular cells reabsorb 85% of filtered bicarbonates and 60% of filtered sodium from the urine, then this again leads to academia. The distal intercalated cells, however, function normally and so the academia is not as severe as in case of Distal RTA. The alpha-intercalated cells can acidify urine to a pH of 5.3 or less because they produce hydrogen ions. Proximal RTA is also associated with Fanconi Syndrome which is characterized by aminoaciduria, uricosuria, glucosuria, and tubular proteinuria.

  Combined distal and proximal RTA
Inherited carbonic anhydrase II deficit leads to combined distal and proximal RTA. This is accompanied by osteopetrosis, cerebral calcification, and renal tubular acidosis. Cases of combined distal and proximal RTA are very rare.

How is RTA understood?
The following steps are applied to analyze Renal Tubular Acidosis-
  Determining the anion gap in acidosis. The normal Anion Gap is 8-12 (4-6 mEq/L)
  Separating the renal from the extrarenal causes of normal anion gap acidosis
  Classifying the types of RTA
  If it is distal RTA, further tests will be necessary to support the diagnosis

How is RTA diagnosed?
Three types of tests can reveal if a person is affected by Renal Tubular Acidosis-
  Urine test
  Acid load test
  Physical examination

Treatment of RTA-
Doctors prescribe either or both of the following two types of therapies-

  Alkali therapy- The pH level of urine is restored and electrolytes are balanced
  Vitamin D supplements- If RTA leads to bone deformities or rickets, your doctor will prescribe vitamin supplements to strengthen your bones.

Timely diagnosis can prevent the effects of Renal tubular Acidosis from becoming compounded. With the right medication, a person can lead a healthy normal life.

What Should You Know About Renal Tubular Acidosis?

Colorectal surgery deals with the disorders of the rectum, anus and colon. Another name of colon is  large intestine . These three body parts form the last stages of the digestive process. When the human waste passes through the colon, its salt and water are extracted before it exits the body as human excreta.

Colorectal disorders

Swelling and inflammation of the veins in the anus (also called as Haemorrhoids)
Anal fissures- unnatural cracks and fissures in the anal area
Fistulas or the unnatural connections between the anus and other anorectal areas
Conditions of constipation
Incontinence in passing of faeces
When the walls of the rectum protrude through the anus- also called as Rectal prolapse
Birth defects such as imperforate anus
Anal cancer- this condition is rare
Colorectal cancer- cancer of colon and rectum
Any injuries to the anus
Removal of any objects inserted into the anus
Bowel habits after colorectal surgery
Many patients report cases of diarrhoea, leakage of stool or gas, urgency to use the toilet and a feeling of insufficient evacuation of faeces. Relax; these conditions are not going to last forever. Your rectum and anus are adjusting to new conditions after this surgery. These organs may take six to twelve months to adjust to new bowel habits.

Is there a need to take a laxative or stool softener?
There is no need to take laxatives after a colorectal surgery. Drink lots of water to make your stool softer and easy to pass. If there is a water deficiency in your body, then it may lead to your faeces becoming hard. In that case, take milk of magnesium, colace etc.

Activities post surgery
You can continue with your normal schedule after this surgical procedure. Carry on running, jogging, exercising, climbing up the stairs etc. even after your surgery. Gastroenterologists recommend that patients should desist from lifting loads weighing more than 10 pounds so that there are no post surgery complications.

Diet after colorectal surgery
Avoid spicy and heavy to digest meals after your surgery. Once the intestines begin working normally, you can continue having your spicy food. Chew your food well to aid its digestion.

Returning to work after colorectal surgery
Most people are back to their work after taking a break of 2-5 days. If the surgery is pretty detailed, you may have to take a break of up to a month. Patients undergoing laparoscopic surgery may have to take a rest of 2- 4 weeks before they report back to work. Take it easy before slipping into your regular schedule. If working hurts after your surgery, don t do it.

Colorectal Surgery - Disorders It Can Treat!

Screening for cancer of the colon or large intestine and rectum is a proven way of saving a person from the impacts of colorectal diseases. This is partly because colon cancer is something that can be prevented if detected at an early stage and the polyps which may advance to cancer are removed properly. Thus if you are turning 50 soon, be prepared to present yourself for a screening colonoscopy that will help you ensure good health and well-being. It may sound uncanny, but do you know that 50,000 people across the world die from colorectal cancer every year, and it is ranked second in terms of cancer-centric deaths.

Understanding the importance of having colonoscopy
You may wonder how a painful, invasive, embarrassing, uncomfortable and time-consuming health test may be called a present. There are reasons enough. A screening colonoscopy is able to expose a cancerous tumour that's presently under way and cast light on the chances and risk factors that may precede it. When you choose to intervene early, you have the power to nip those risks at their budding stage, much before those malicious cells become malignant.

Spreading of the colorectal cancer
Your large intestine is really a big and last organ of the gastrointestinal system where the small intestine discontinues. Its primary function is to remove the water out of the leftover solids of digestion and get rid of them in the form of stool. Cancer may start to develop anywhere within the tube that expands 5 feet long and squares the vacant area of the abdomen. The large intestine expands up towards the right side, i.e. the ascending colon and then turns left through the liver, i.e., the transverse colon, bending down right at the spleen on its left, i.e. descending colon and loops to the middle, i.e., the sigmoid colon before it runs across the rectum and ends at the anus.

People who need a colonoscopy
To simplify matters, it can be said that all adults are at a potential risk of the colorectal cancer, including those people who lead a healthy life. But some people are at a higher risk. Those individuals have a specific gene mutation that predisposes them to develop into numerous polyps. The risk is also high with people who are first-degree relatives of a person diagnosed with cancer before the age of 50. People with Ulcerative colitis, various types of inflammatory bowel diseases and Crohn's disease are also at a higher risk.

Colorectal cancer is a serious ailment and screening colonoscopy is a feasible means of detecting any polyps that may be cancerous in the future. Speak with a reputed gastroenterologist today to stay ahead of the disease.

When Should You Start Having Colonoscopies?

An apple a day keeps the doctor away, but Minions seem to disagree. An apple being the fruit of choice for millions of households across the world, recent studies show that apples may not be as good for you as you ve been led to believe. For starters they have high sugar content, for the calorie conscious, which might be a bad revelation. The really high fiber content of apples is known to induce stomach aches. Studies show that most apples in the regular market are laden with pesticides, which are harmful for human consumption. Apples are known to cause allergies too and not to forget, apple seeds contain trace amounts of cyanide.

So if not apples, what is supposed to keep the doctor at bay? The world is going ga ga over bananas. Bananas and papayas are two easy to resource, lower priced alternative as the household fruit of choice. Here s why.

Papayas and Bananas contain fewer carbohydrates and more protein than Apples and hence instantly making them a better choice for calorie conscious.
High levels of Tryptophan, make bananas and papayas a natural antidepressant and stress buster.
Both are rich in Anti oxidants which helps in preventing and fighting cancer.
Bananas protect an individual against type 2 diabetes and aid in weight loss in this new age of morbid obesity that makes it quite a selling point.
Both fruits being rich in vitamin C are known to boost immunity.
Papayas are rich in flavonoids, vitamin A and beta carotene, which protect the mucus membrane of the eye and are known to prevent age related retardation of eye sight.
Bananas and Papayas help prevent swelling of joints and work well to prevent arthritis.
Both fruits are known to help ease menstrual cramps.
Papaya is rich in vitamin E, vitamin C and antioxidants like beta-carotene which helps prevent your skin from free radical damage keeping wrinkles, marks and signs of ageing at bay.
Papaya is known to encourage hair growth and fight against hair fall.
The duo is known to improve overall digestion as well.
