Top 10 Most Common Diseases and Health Issues

The health problems that are the most frequent in worldwide population nowadays are listed below. They all have a very high incidence and humans face them very often during their lifespan.

10. High Blood Pressure


9. Hepatitis A and B

Hepatitis B
is an infectious illness caused by hepatitis B virus (HBV) which infects the liver of hominoidea, including humans, and causes an inflammation called hepatitis. Originally known as “serum hepatitis”, the disease has caused epidemics in parts of Asia and Africa, and it is endemic in China. About a third of the world’s population, more than 2 billion people, have been infected with the hepatitis B virus. This includes 350 million chronic carriers of the virus. Transmission of hepatitis B virus results from exposure to infectious blood or body fluids.

8. Diabetes

There are three main types of diabetes:

7. Digestive Problems

These include Constipation – one of the most common diseases of the digestive system. Constipation simply means temporary loss of smooth bowel movement. In this condition, going to the toilet for bowel evacuation is a painful activity. This happens because the fecal matter is hard and hence eliminating it out of the body can bring lot of discomfort; Diarrhea – Diarrhea causes frequent bowel movement and is typically marked by defecation of watery stools. This is basically a viral infection that usually subsides on its own without any medical treatment. Staying away from diary products is often recommended as they aggravate symptoms of diarrhea; Irritable bowel syndrome (IBS) - is a digestion problem in which the large intestine (colon) is not in a position to work efficiently. This condition typically causes abdominal pain, boating gas, stomach cramps and alternating bouts of diarrhea and constipation. Fortunately IBS is not worrisome as the colon does not suffer from irreversible damage. As the cause of IBS is unknown, taking appropriate medication to relieve symptoms is prescribed; Stomach ulcers – A stomach ulcer is an open sore formed by the erosion of a small area in the mucus membrane lining the stomach. The eroded part lining the stomach is often the result of H.pylori infection that typically reduces appetite, eventually leading to weight loss. H.pylori is a bacterium and so treatment involves taking antibiotics for a stipulated period of time.

The most common disease is periodontal disease—disease of the gum, bones, and/or connective tissue that support the teeth. An example of periodontal disease is gingivitis, the inflammation of the gums.

More people get tooth decay, or cavities, than any other disease. Almost everyone in the world has a cavity sometime during his life.
