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?

Rectal problems in women are quite common. It is experienced by many women in some form or the other such as rectal itching, pain or bleeding. Rectal problems are more common in women than in men. These conditions need to be attended to immediately as severe rectal problems may cause several health problems. There are many ways to deal with rectal problems in women.

Treating rectal itching: Rectal itching is a common rectal problem. These can be treated by

    Improve hygiene: You should clean the rectum area gently using cotton balls moistened with water. You should apply mild ointments to prevent irritation and soothe the skin.
    Unscented toilet paper or unscented lotions and creams: You should use white toilet paper that does not have any scent. Scented soaps, creams or lotions should be avoided as it may cause further irritation. You can also apply ointments containing 1% hydrocortisone.
    Control excessive sweating: Rectal problems may occur due to excess sweating. You should avoid sweating too much by wearing light clothes and using talcum powder for the absorption of moisture.

In case of excessive itching, you should follow the following tips:

    Do not scratch the area as scratching may lead to further itching. You can take an oral antihistamine during the night to get better sleep.
    You can take a warm sitz bath after every bowel movement, for at least three days, every day. The anus should be dried properly after the bath.
    Abstain from foods that stimulate rectal itching like tea, coffee, aerated drinks, alcohol, chocolate, spicy food, tomatoes and excess vitamin C, for a period of two weeks.
    You must maintain short fingernails to avoid injuries during scratching. To prevent unconscious scratching during sleep, wear cotton gloves.
    Stress should be managed as increased stress may lead to enhanced rectal itching. When you are anxious, do not scratch the rectal area.

Treating rectal bleeding: Rectal bleeding is another problem, which may be accompanied by other rectal problems. In case of rectal bleeding, avoid taking aspirin or any other non-steroidal, anti-inflammatory drug. These drugs may cause bleeding in the digestive tract. This will increase the blood amount in your stool. Bleeding hemorrhoids can worsen by the intake of these medicines. For soothing pain, opt for an acetaminophen. Constipation and diarrhoea may also lead to rectal bleeding. However, it is advised to consult a doctor before consuming any medicine.

Prevention
For prevention of rectal problems, you must have a good sense of hygiene. Keep the rectum region clean and avoid sitting in the toilet for a long time. You should have a fiber-rich diet including fresh fruits and vegetables. Avoid food items, which may cause rectal problems. General rectal problems are not very serious and can be treated using simple measures. Maintaining proper rectal hygiene is very important to avoid rectal problems. It is highly recommended to visit a doctor if the problem persists.

Rectal Problems in Women - Doctor Recommended Tips

Colorectal surgery is the broad term for surgical procedures performed on the colon, the rectum and the anus. There are various different surgical procedures which fall under colorectal surgery and these are used to treat a vast array of disorders, such as:
1. Anal cancer
2. Colorectal cancer
3. Severe complications related to constipation
4. Anal injuries
5. Inflammatory conditions of the gastrointestinal tract
6. Congenital defects

Procedures
The surgeries under colorectal surgery are performed after diagnostic tests such as proctoscopy, sigmoidoscopy and defecating proctography. The most common diagnostic test is colonoscopy. These help to identify the origin and nature of the problem and decide which surgical procedure is to be followed. The procedures under colorectal surgery are as follows:

Colectomy
This procedure involves removal of a section of the large intestine. This is known as partial colectomy. In extreme cases, such as advanced cancer or severe gastrointestinal infection, the entire colon is removed and this is called total colectomy. Sometimes, the rectum is also taken out along with the colon and this is called proctocolectomy.

Colonic polypectomy
An abnormal growth of tissues in the inner lining of an organ is known as a polyp. Colonic polypectomy is done to eliminate polyps from the colon and rectum before they become malignant. This can be done endoscopically. Surgery is required in case of large polyps.

Strictureplasty
Chronic or repeated bowel inflammation causes scar tissue to accumulate in the large intestine. This results in the narrowing of the colon. Stricturoplasty removes the scar tissue so that proper flow of digestive contents is resumed.

Colostomy or ileostomy
A damaged section of the colon is removed and the shortened intestine is then attached to another opening (stoma) in the anterior wall of the abdomen.

Hemorrhoidectomy
This surgical process is used for swollen hemorrhoids or blood vessels, which form in the anal canal. Hemorrhoidectomy is extremely effective in removing hemorrhoids, but the surgery also involves a number of complications.

Anoplasty
Anoplasty or imperforate anus correction is done to correct birth defects in the rectum and the anus. The structural flaw does not allow the stool to pass properly from the rectum and so it is repaired through surgery.

All About Colorectal Surgery

An anorectal abscess is a painful swelling near the anus or in the buttock. The swelling contains pus. 60% anorectal abscesses are superficial and resulting from infection in small anal glands present in between internal and external anal sphincters (intersphincteric space). They are known as a perianal abscess. 30% of anorectal abscesses are deep-seated and results in systemic infection. They are call Ischiorectal abscess. Submucous abscess, pelvirectal abscess and pilonidal abscess developed from versatile cause are comparatively less common. Inadequate and improper management of anorectal abscess may potentially cause complication like fistula formation.


Fast facts on Anorectal abscess-

* Anorectal abscess should be drained at the earliest.
* Conservative medical management almost invariably invites complication like fistula formation.
* Surgical drainage of pus reduces the chance of fistula formation by 50%.


What causes Anorectal abscess?

* Blocked and infected anal glands (cryptoglandular infection).
* Untreated anal fissure that becomes infected.
* Sexually transmitted infections.
* Penetrating injury of the perianal or buttock region.
* Crohn s disease.
* Colon cancer.
* Tuberculosis.



What are the symptoms of Anorectal abscess?

Superficial abscess-

* Constant and throbbing pain that worsens on sitting down.
* Swelling, redness and tenderness of the skin around the anus.
* Discharge of pus.
* Pain is often associated with bowel movement.

Deep abscess-

* All or some of the symptoms of a superficial abscess.
* Fever with chill and rigor.
* General weakness.
* Sometimes fever is the only symptom of the deep abscess.

The anorectal abscess should preferably be explored under general or spinal anesthesia. Medical management often fails and subsequently fistula is formed.

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?

If you notice blood in the stool or the toilet bowl, it could be a case of rectal bleeding. There are many reasons why rectal bleeding can occur, the most common one being haemorrhoids. If the rectal bleeding is not significant then it is not a cause for concern. But if you lose a lot of blood then it can be a major problem.

What are the signs?

The most obvious one, in this case, is the presence of blood in your stool. But it's not just the presence of blood that is important here, the colour of the blood is also a very important indicator of what is wrong.

Black colour indicates that you are bleeding from the upper region of the small intestine

A bright red colour is an indication of the blood loss from the lower part of the gastrointestinal tract   rectum or colon

Dark red indicates that the bleeding is taking place at the initial region of the colon

Some other symptoms you may experience are  

Confusion

Pain in the rectum

Stomach cramps

A sensation of dizziness

Causes of rectal bleeding

Causes of rectal bleeding can be divided into mild and serious. 

Mild causes  

Constipation 

Small tears in the anal lining (anal fissures)

Haemorrhoids

Small growths of tissue in the rectum or colon

Serious causes  

Cancer of the colon and anus

Inflammatory bowel disease

An infection of the intestine such as salmonella

How is it treated?

If you lose a lot of blood, then it is a medical emergency. You should rush to the doctor if you experience the following   fainting, intense pain in the stomach, confusion, and rapid breathing.

The doctor will prescribe treatment based on the cause of your rectal bleeding. For example, if the cause is haemorrhoids then warm baths will help soothe the pain. If the haemorrhoids are large then invasive methods such as laser treatments and surgery are prescribed. 

Or if it is constipation then stool softeners are a good option. In addition, you may have to eat a high fibre diet and exercise regularly to normalize your bowel movements. 

Rectal bleeding can be a minor inconvenience or a major problem depending on the cause. So it is best to consult a doctor and seek immediate treatment.
