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?

Bariatric surgery is unlike other surgeries, as its effects are not instant but gradual and are seen over the months. Like any other surgery, it is not without complication. But again unlike all other surgeries, the complication rate can be negligible if a strict protocol is followed. Moreover, the factors like technology advancements, development in the field of advanced laparoscopy, enhanced skillset of the bariatric surgeon, dedicated management of bariatric and metabolic surgeries by bariatric surgeons, play a vital role in the reduction of complication rate which eventually results in safe surgery.

As the procedure is done laparoscopically, the pain is just for a day and is minimally managed by analgesics.

The fear of increasing incidence of incisional hernias while operating an obese patient is so negligible or nil, as the procedure is performed through tiny key holes and all precautions are taken to suture the sheath through which the ports are put to perform the surgery.

Reduced hospital stay and early resuming to work is one of the biggest benefits of this laparoscopic bariatric procedure.

Sometimes, problems that may be faced are:- 

Post-operative bleeding: Normally, this a nearly bloodless surgery involving 5 to 10ml loss of blood. However bleeding from the staple edges is known, but this can be managed well by the surgeon, by choosing the right size of the cartridge as well the right technique of application of the cartridge.

Dehydration: We are normally accustomed to drinking water at long intervals (a few hours) as we can consume nearly 200 to 400ml at one go. Following bariatric surgery, gulping or drinking water in one go is not possible in the first 2 to 4 weeks, due to reduced capacity of the gastric pouch. Hence, care needs to be taken to drink small quantities of water at frequent intervals to avoid dehydration. This is possible only if the patient is counselled about this prior to surgery and is fully aware of this. Also, the patient needs to be given good and clear post operative instructions regarding the quantity and frequency of liquid consumption, not forgetting the type of liquids. Coffee taken frequently could be another cause for dehydration. Family members and colleagues and friends at work play a major role in reminding tthe patient about consuming water frequently. Special care needs to be taken in people who are not accustomed to consuming adequate quantities of water prior to surgery as a general habit.

Vomiting/Fullness/ Discomfort/Indigestion: Following bariatric surgery, soft food is introduced in the diet in the third week, after the first 2 weeks of taking liquids. Due to the reduced capacity of the gastric pouch, the morsel size is significantly reduced and one has to chew the morsel well and eat slowly, giving a gap of 40 to 50 seconds between the morsels. This prevents distension or overdistension of the gastric pouch and thus avoids vomiting. This again requires good counselling prior to the surgery and on the follow up visit too before stating soft food. There is a subjective difference when we say small morsels and we cannot reach a standardization as the morsels size of each individual varies prior to the surgery itself. The best way to avoid this confusion is to make the person have the first soft food meal before you where in you can physically show the way food is expected to be eaten. However, by mistake, there is a chance that one can have a regular sized morsel as over years one is used to eating in that manner. If this happens, the person will vomit , and this will be a reminder to gauge the morsel size the next time the person eats. Following the vomiting, there could be a burning sensation in the stomach which will subside afer taking an antacid. If one follows the instructions of small morsel size, chewing properly and eating slowly, there is no chance that there will be vomiting. Another reason for vomiting could be keeping the stomach empty for a longer duration or having sicy food on an empty stomach. Avoid nuts, seeds, fried foods and processed foods. Very rarely vomiting could be due to reduced size of the joint between the gastric pouch and the small intestine. This could require an Endoscopy and necessary treatment.

Vitamin and mineral deficiency: It is seen that many of the obese patients are seen to have vitamin B12, vitamin D, iron and protein deficiencies in their blood tests that are done prior to surgery. With the significant reduction in the amount of food consumed after bariatric surgery, the existing deficiencies are bound to increase. Hence, it is necessary to do these tests, before surgery and rectify the deficit prior to the surgery.  

Gall bladder stones: Significant weight loss which is consistant over a short duration could lead to the formation of gall bladder stones, be it with or with out surgery in a small percentage of patients. To avoid this there are two schools of thought, one is have a prophylactic removal of the gall bladder along with the bariatric surgery and another is to put the patient on ursodeoxycholic acid (a tablet) for the first few months after surgery during which there is significant weight loss.

Skin sagging: In the morbidly obese, when the skin is overstretched beyond a certain point, it tends to sag once significant weight is lost. This sagging is influenced by a number of factors like age of the patient, the BMI, pre existing sagging, pre-existing muscle tone and protein supplements taken during weight loss and exercises done during the weight loss period. Skin sagging is less if the age is less than 45, BMI less than 45, good protein intake during weight loss and good toning exercises done during the weight loss period.

Hairfall: Significant weight loss either by diet and exercise, aerobics, bariatric surgery, will entail hair loss. But this can be minimised to a greater extent by ensuring good protein intake during the weight loss period and adequate supplements in terms of vitamins and minerals.

Dumping syndrome: With a reduced size of the stomach, the food moves from the stomach into the smaller intestine much faster. This causes the pancreas to release excessive amount of insulin, leading to very low blood sugar levels , producing various symptoms like abdominal cramps, bloating, diarrhoea, sweating, dizziness, nausea, weakness, and anxiety. This is managed by eating less amount of sugars and fats and spacing out the meals through the day, having four to five small meals compared to  2 to 3 large meals. Having a high protein diet and avoiding liquids during meals is also an option.

Bariatric Surgery - Know Problems Of It!

This surgery involves the removal of Gallbladder, which is a pear-shaped organ that lies right beneath the right side of the liver. The main function of the gallbladder is to collect and concentrate bile, which is a digestive juice produced by liver after eating, aiding digestion. The most common disorder of the digestive system is presence of Gallstones, which are the stones made up of a mixture consisting of cholesterol, bile pigment and calcium salts.

These Gallstones don t cause any problems in most cases. But prompt treatment is required if stones block ducts and cause infections and inflammation in the pancreas. This may lead to removal of the gallbladder through a surgery, known as cholecystectomy, which further includes techniques such as laparoscopic (keyhole) cholecystectomy or open surgery.
Although it is a less vital organ, the body can cope up even after removal.

Procedure of surgery:

    The surgery involves removal of gallbladder and gallstones through several incisions in the abdomen. In order to see clearly, the surgeon inflates the abdomen with air or carbon dioxide.
    A lighted scope attached to a video camera is inserted into one incision near the belly button. The video monitor is used as a guide for inserting other surgical instruments into the other incisions to remove the gallbladder.
    Intraoperative cholangiography is the X-ray procedure which shows the anatomy of bile ducts. This is done before the surgeon removes the gallbladder.
    Bile flows from the liver through the common bile duct after the surgery into the small intestine. As the gallbladder has been removed, the gallbladder can no longer store bile between meals but has no effect or little effect on digestion.
    In case of open surgery, the surgeon reaches the gallbladder through a large, single incision in the abdominal wall.

Complications after gallbladder surgery:
This surgery carries some degree of risk like any other surgery. Complications such as internal bleeding, infection, injury to nearby digestive organs, injury to the bile duct and injury to blood vessels.

Types of gallstones:
There are three main types of gallstones. They are
1. Mixed stones: They are made up of cholesterol and salts. They tend to develop in batches.
2. Cholesterol stones: Mainly made of cholesterol, which is crucial to many metabolic processes. They can grow large enough to block the bile ducts.
3. Pigment stones: The colour of bile is greenish-brown, due to some particular pigments.

Medical factors to consider before cholecystectomy:
The most important factor is a consideration of your medical history. This is because the pre-existing conditions influence decisions on surgery and anaesthetic and information about any bad reactions or side effects from any medications would be helpful for surgery.

Self-care after the surgery:
Taking rest is the most important thing after surgery. Avoid things such as heavy lifting and physical exertion. The usual recovery period after the surgery is one week. 

Gallstone Surgery - Things You Should Know About It 

Benign prostatic hyperplasia or BPH is a condition where the prostate gland gets enlarged. This is mostly common in men who are ageing. When the prostate gland gets enlarged, the flow of urine through the urethra gets blocked, and hence, several problems related to urination may occur. BPH occurs as a result of hormonal imbalance. If untreated, BPH can lead to severe bladder and urinary health conditions.
There are several symptoms and signs of benign prostatic hyperplasia. Here are 7 common symptoms:

1. A frequent need for urination: Men affected by BPH feel an increased need to urinate frequently. This gets enhanced during the night and is called nocturia. The patient may even need to urinate more than eight times a day. Due to the enlarged prostate gland, more pressure is put on the urethra, which leads to uncontrollable urination.
2. Urinating difficulties: The act of urination becomes difficult. Because of enhanced pressure on the urethra, the flow of urine to the penis from the bladder gets blocked. This makes a urine stream hard to start. The urine stream gets weak and interrupted, and more difficulty may be experienced during the end of urination.
3. Pain during urination and ejaculation: Due to pressure on the urinary tract and reproductive system, pain can accompany urination and ejaculation. Some patients tend to push urine out, which results in pain. The pain may also occur because of infection during BPH.
4. Blood in urine and an unusual color/smell: Urine may take a dark color and have an unusual smell due to urinary retention. Unpleasant urine smell signifies urinary tract infection. Blood in the urine may also result because of dilated veins present on the surface of the enlarged prostate.
5. Urinary retention: When a patient is unable to pass any urine, it is called urinary retention. Such a condition requires immediate treatment, and you need to consult a doctor immediately.
6. Urinary tract infections: Bacteria may start growing in the bladder when the bladder is not fully emptied of urine. This bacterial infection causes darkening of the urine, and emission of a foul odor.
7. Bladder stones: Bladder stones may develop because of the inability of the bladder to empty itself completely. This is a major symptom of BPH. Hard lumps of minerals or bladder stones are formed when the urine present in the bladder gets highly concentrated, which causes the crystallization of minerals. Bladder stones may cause infections, result in blood in urine, cause bladder irritation and may also block urine flow.

So you see that benign prostatic hyperplasia involves the enlargement of the prostate gland, and results in several problems related to urination and different symptoms. Hence, immediate treatment is advisable.

7 Symptoms of Benign Prostatic Hyperplasia

The liver has a significant role to play in metabolism and digestion. The failure of a liver can lead to significant health issues. There are some causes for liver failure, which cannot be treated with medications. In these people, a transplant, which is replacing the diseased or injured liver with another liver, is the only definitive treatment option.

Some conditions which can require a liver transplant are:

Severe cirrhosis with a life expectancy of less than a year
Severe liver failure
Non-alcoholic steatohepatitis (NASH)
Liver cancer
Chronic hepatitis C
Biliary atresia in children
Types of transplant:

Living donor transplant: In some patients, partial liver can be removed from a close family member and transplanted into the affected individual. The liver is known for its regeneration ability, and over time, will grow in the recipient.
Cadaveric transplant: Immediately after death, a liver can be removed and transplanted.
While the concept of a transplant sounds quite convincing and appealing for those with a severe liver disease, it is also important to note that not all would qualify for a liver transplant. The conditions which would disqualify a recipient are discussed below:

Significant heart disease: Those with severe coronary artery disease, valvular disease, cardiomyopathy, aortic stenosis, and cardiomyopathy are not candidates for a liver transplant.
Severe lung disease: Those with poor lung perfusion do not qualify for a liver transplant.
Advanced age: Greater the age, lesser the survival rates. So, people aged more than 70 are usually not considered for a transplant.
Obesity: A person with a BMI of more than 35 is often not a good candidate for a transplant. The overall health should be managed in these people.
Malnutrition: On the other extreme, severely malnourished individuals are also not considered for a transplant.
HIV infection: A person who is HIV-infected does not qualify for a liver transplant.
Substance abuse: Anyone who is actively abusing alcohol and/or substances is definitely removed from the list for a transplant.
Metastasis: If a patient is looking for a liver transplant due to hepatic cancer, it is essential that the cancer is contained. If it has spread to various parts, then containing it would be difficult, and a transplant may not succeed.
Multisystem organ failure: Other than heart and lungs, even people with poor renal function are not ideal candidates for a liver transplant.
A detailed liver recipient evaluation assessing the severity of liver disease, chances of survival, and overall health are done before a person is listed for liver transplant. This evaluation ensures a better success rate with the transplant.

Common Surgical Complications That One Should Be Prepared For?

Homeopathy can very well dissolve gall stones of small and medium sizes, and relieve the gall bladder and body permanently from the pain, suffering and complications coming from gall stones. One of the benefits of homeopathic treatment for gall stones is that your gall bladder does not need removal, and being an important organ for producing digestive enzymes, it is better to keep it in your body.
