What is Diabetic Coma?

Coma is a medical emergency or a state of unconsciousness calling for immediate evaluation to determine its cause. It is only when sugar in blood is being used properly that fat can also be oxidized or burnt to provide heat and energy; when fat cannot be utilized a condition called acidosis develops and when this is present to a serious extent it affects the nervous system and causes diabetic coma.

Are you a Obese person?

A person is said to be obese if his/her Body Mass Index is greater than 30. It can be calculated by dividing ones weight in Kilograms by Height in meters²

AIDS - Acquired Immuno Deficiency Syndrome

Discovery of AIDS

Homosexual men with symptoms of a disease that now are considered typical of the acquired immunodeficiency syndrome (AIDS) were first described in Los Angeles and New York in the year 1981. The men presented with an unusual type of lung infection called Pneumocystis carinii (now known as Pneumocystis jiroveci) pneumonia (PCP) and rare skin tumors called Kaposi's sarcoma.

Hiccups - Causes and Home remedies

What is hiccups?

Hiccup is a condition that is experienced by every human being. The sound ’hic’ comes from the opening and closing of the mucous membrane which attached to the larynx.

Foodborne Illnesses - Prevention, Diagnosis and Treament

Prevention of foodborne illnesses

Foodborne illnesses can be prevented through proper cooking or processing of food, which kills bacteria. In addition, since the bacteria multiply rapidly between 40°F and 140°F, food must be kept out of this temperature range.

Foodborne Illnesses - Causes, Symptoms and Complications

What are foodborne illnesses?

Eating food or drinking beverages contaminated with bacteria, parasites, or viruses is the cause of foodborne illnesses. Harmful chemicals can also lead to foodborne illnesses if they consume contaminated food during harvesting or processing. Foodborne illnesses can cause a number of symptoms that range from an upset stomach to more serious symptoms, including diarrhea, fever, vomiting, abdominal cramps, and dehydration.

Gallstones

What are gallstones?

A small pebble-like substance that develop in the gallbladder is called gallstone. The gallbladder is located below the liver in the right upper abdomen. It is a small, pear-shaped sac that stores bile, a liquid that helps the body to digest fats.When the liquid stored in the gallbladder hardens it forms into pieces of materials called stones.


Composition of Bile

Bile is a golden yellow or greenish fluid poured into the digestive tract along with the pancreatic juice. This helps in the digestion and absorption of lipids. The contents of bile are:

1. Water

2. Cholesterol

3. Fats

4. Bile salts

5. Proteins

6. Bilirubin

Bile salts are nothing but sodium and potassium salts of bile acids conjugated either with glycine or taurine. They are needed for the solubilisation of fats. Bilirubin is the excretory product of bile and is the important bile pigment which is responsible for the yellowish-brown color of the faeces. If enormous amounts of bilirubin, bile salts and cholesterol are present it hardens and this forms gallstones.


Types of gallstones

1. Cholesterol stones

They are usually yellow-green and are the primary content is cholesterol, which is hardened. About 80 percent of gallstones are cholesterol stones.

2. Pigment stones

They are small and dark stones made only of bilirubin.


Size of gallstones

The size of the gallstone may be as small as a grain of sand or as large as a golf ball. The gallbladder can develop into

a. one large stone

b. hundreds of tiny stones

c. a combination of the two


Causes for the formation of gallstones

Stones develop in people with liver cirrhosis, biliary tract infections, or hereditary blood disorders because bilirubin is formed in large quantities in these conditions.


Factors that contribute to the formation of gallstones

Sex

Women are more prone to develop gallstones when compared to men. This is due to excess estrogen production due to pregnancy and hormone replacement therapy, which increases the cholesterol levels in bile and thus leads to gallstones.

Family history

Gallstones often develop in families as a genetic link.

Weight

Obese persons are more prone to get gallstones due to increased cholesterol levels.

Diet

A Diet high in fat and cholesterol and low in fiber can increase the risk of gallstones.

Age

People who are above 60 are more likely to develop gallstones than younger people. The body tends to secrete more cholesterol into bile as the age increases.

Cholesterol-lowering drugs

Some drugs that are used to lower cholesterol levels in the blood may increase the amount of cholesterol secreted into bile thus increasing the risk of gallstone formation.

Diabetes

Diabetic individuals usually have high levels of fatty acids called triglycerides which may increase the risk of gallstones.


Symptoms of gallstones

Gallstones move from the gallbladder and lodge in any of the ducts such as hepatic duct, cystic duct and common bile duct and thus causes blockage of bile flow. A gallbladder attack may occur suddenly following a fatty meal due to this blockage particularly during night time.

1. Steady pain in the right upper abdomen.

2. Pain in the back between the shoulder blades

3. Pain under the right shoulder

4. Prolonged pain lasting for more than 5 hours

5. Nausea and vomiting

6. Fever

7. Yellowish color of the skin or white layer of the eyes

8. Clay-colored stools


Diagnosis of gallstones

1. Computerized tomography (CT) scan

2. Cholescintigraphy (HIDA scan)

Peptic Ulcer

What is a peptic ulcer?

A peptic ulcer is a small sore which occurs in the mucous membrane. Mucous membrane is the membrane lining hollow organs of the body such as stomach and duodenum. Any destruction to this lining causes peptic ulcer. The destruction is caused due to bacterial infection or by the long-term use of nonsteroidal anti-inflammatory agents (NSAIDs), like aspirin and ibuprofen. Cancerous tumors in the stomach or pancreas may also cause ulcers in a few cases.

Appendicitis

What is appendicitis?

A painful swelling and infection of the appendix is called appendicitis.


What is appendix?

A fingerlike pouch attached to the large intestine and located in the lower right area of the abdomen is an appendix. The hollow space inside the appendix is called the appendiceal lumen via which the mucus created by the appendix travels and empties into the large intestine.

Lactose intolerance

What is lactose intolerance?

Lactose is the major sugar found in milk. The inability to digest significant amounts of lactose is called lactose intolerance.

Enzyme deficient

The enzyme lactase produced by the cells that line the small intestine is deficient. Lactase is responsible for the breakdown of the milk sugar into two simpler forms of sugar called glucose and galactose. This simple sugars are then absorbed into the bloodstream. If this enzyme is deficient lactose accumulates and thus leads to lactose intolerance.

Acute pancreatitis

What is pancreatitis?

Inflammation of the pancreas is called as pancreatitis. The pancreas is a large gland which is behind the stomach and close to the duodenum.

Chronic pancreatitis

What is chronic pancreatitis?

An inflammation of the pancreas that does not heal or improve and gets worser and worser leading to permanent damage of the pancreas is called as Chronic pancreatitis.

Cirrhosis

What is cirrhosis?
