Cirrhosis
The liver is responsible for neutralizing the blood of toxins, germs and bacteria as well as producing immune agent to contrl infections. Bile, critical to the absorption of fats and fat-soluble vitamins is made by the liver. Cirrhosis is a condition where the liver is affected by irreversibble scar tissue leading to its damage and consequent failure. Blood flow to the liver is then affected. Symptoms of cirrhosis range from exhaustion and fatigue to weight loss and abdominal pain. A person suffering from liver cirrhosis may experience abdominal pain and loss of appetite. There are noticeable red spider veins under the skin and the skin and eyes may turn yellow. There is decreased interest in sex and edema (swelling on hands and legs) might be noticed. A person suffering from cirrhosis and damaged liver may notice an increased tendency to bruise and bleed easily. Intense itching is felt on account of the bile products being deposited in the skin. Gallstones may develop as a result of inadequate bile reaching the gallbladder. There might be a buildup of toxins in the brain bringing about bouts of unresponsiveness and forgetfulness. Cirrhosis can bring on Portal hypertension - a condition where there is reduced flow of blood to the portal vein and increased pressure within it. Cirrhosis can eventually lead to liver cancer caused by carcinoma. Impotence, kidney dysfunction and osteoporosis are other likely complications of liver disease.
Cirrhosis of the liver is usually caused by chronic alcoholism or hepatitis C. Other possible factors leading to cirrhosis are problems in the immune system and damaged bile ducts.
Chronic Alcoholism - One of the common causes for cirrhosis is alcoholism. But this condition occurs only after atleast 10 years or more of heavy drinking. Alcohol affects the liver's ability to metabolise proteins, fats and carbohydrates.
Chronic hepatitis - Hepatitis C virus can lead to severe inflammation and damage of the liver, thereby causing cirrhosis. Hepatitis B is one of the most common causes of liver inflammation in many of the developing nations.
Blocked bile ducts - In such a condition, the bile is unable to travel out of the liver and instead ends up damaging liver tissue. This can be a congentinal defect in some infants.
Cirrhosis of the liver can cause many other abnormalities. It can leads to elevated levels of triglycerides, cholesterol and sugar. Diabetes mellitus is a common fallout. There might be a fall in platelet count and GI bleeding. In severe cases of cirrhosis, there can be an immune system dysfunction or even brain swelling and later coma. The liver of an affected person will feel be larger and harder to touch. A liver scan or ultrasound can help detection of cirrhosis. A liver biopsy is sometimes resorted to. Damage to the liver due to cirrhosis cannot be reversed but further complications can be reduced with the right treatment. Cirrhosis caused by excess alcohol consumption needs lifestyle changes such as avoiding alcohol and following a nutritious diet. Low-sodium diet can help drain excess fluid-buildup within the body. Chronic viral hepatitis B and C are treated with prednisone and azathioprine. Any bacterial infection is treated with appropriate antibiotics. Liver transplantation surgery is done on cases where the liver is not capable of functioning. With the help of modern drugs such as cyclosporine and tacrolimus, the success of liver transplantation surgery has risen manyfold.
Acute Glomerulonephritis
Glomerulonephritis is a medical condition where the glomeruli in the kidneys become inflamed. The glomeruli are involved in the removal of uremic waste. Acute Glomerulonephritis occurs when the inflammation is sudden and severe. Children in the age group 2 - 12 years are more likely to suffer Acute Glomerulonephritis. This disease can also affect those suffering from diabetes, hepatitis or lupus. Typically Acute glomerulonephritis follows a streptococcal infection, such as strep throat, tonsillitis or scarlet fever. Viral infections such as HIV or hepatitis B or hepatitis C can bring on an attack of acute glomerulonephritis.
Symptoms of glomerulonephritis include fatigue, nausea and loss of appetite. There might be flu-like symptoms including fever. Joint pains and blood in the sputum are also noticed in patients suffering from glomerulonephritis. Shortness of breath and high blood pressure may be experienced. There might be blood and protein in the urine. Often Chronic glomerulonephritis is not manifested in any symptoms and is discovered only with a physical examination. Complications such as high blood pressure and kidney failure can occur if it is left untreated.
Mild cases of glomerulonephritis are not treated unless the symptoms become severe. CT scan allows the doctor to visualize the kidneys. Urine is checked for increased levels of protein. Blood tests reveal any streptococcal antibodies or low blood count. A biopsy is often done to determine the cause for Glomerulonephritis.
Treatment for acute glomerulonephritis involves improving the functioning of the kidneys and reducing the damage to the glomeruli. A diet with reduced intake of sodium, protein and fluids is recommended. The patient suffering from acute glomerulonephritis is advised bed rest to facilitate better blood flow to the kidneys. Antibiotics are often prescribed to treat residual infection. Diuretics aid in better output of urine. In cases of renal failure, temporary dialysis or kidney transplant are considered.
Gastroenterologist
Physicians who specialize in the diagnosis and treatment of the digestive system or gastrointestinal tract are gastroenterologists. When they specialize to treat children in the same area, they are termed as pediatric gastroenterologist. They treat conditions such hepatitis, colon or rectal cancer, ulcerative colitis and Crohn's disease. A gastroenterologist must complete four years of degree, four years of medical school, three years residency in internal medicines and later specialize in gastroenterology for a period of two to three years. Certification from a recognized board is necessary.
Role of gastroenterologist
Diagnose and offer medical treatment for any kind of disorder in the gastrointestinal tract.
Order for blood tests, x-rays, endoscope checks of the stomach called gastroscopy or for the large intestine called colonoscopy depending on the patient's illness.
Assist a surgeon in exactly locating the area of problem that needs treatment in the gastrointestinal section.
They follow up digestive system disorders that include esophagus, small and large intestine, stomach, pancreas and the liver. They also follow up on symptoms of heartburn, indigestion, ulcers etc following an operation.
Modern techniques and gastroenterologist
Use of ultra high frequency in endosonography gives better understanding of any lesions formed.
Measuring of myoelectric and contractile activity in the gastrointestinal tract, esophageal and anal manometry to understand constipation, nausea, abdominal pain etc better in any patient.
Electrogastrography and few other modern techniques have made it easier to understand the esophageal transit in patients easier.
