Diarrhea: Symptoms, Causes, Diagnosis, Prevention & Treatments post thumbnail image

Diarrhea is a common health problem. It can begin from being a mild, temporary condition and develop into a potential life-threatening problem.

There are about 2 billion diarrhea cases recorded every year across the world, with approximately 1.9 million cases of death of children of age below 5 years, typically in developing countries.

Meaning/ Definition of Diarrhea:

Diarrhea means getting loose, watery stools three or more times a day. Usually, it lasts for a couple of days. Diarrhea can either be acute or chronic. When it lasts for more than a few days, it is acute diarrhea. This could be a sign of a bigger problem. Chronic diarrhea lasts for around four weeks – which may be a symptom of a serious disease. It usually results from an intestinal problem or disorder, like celiac disease or Crohn’s disease.

There are some people who pass stools very often, but that is not diarrhea as they are of normal consistency. Likewise, breastfed infants also pass loose, pale stools. This is also not diarrhea.

Types of Diarrhea:

  • Microscopic colitis : This type of diarrhea majorly affects the elderly people, causing trouble most often during the night time. It can continue for a long time and may not go away completely in some cases.
  • Mal-absorptive and Mal-digestive diarrhea : Sometimes, non-absorption of food nutrients can cause mal-absorptive diarrhea. While non-functioning of the digestive system leads to mal-digestive diarrhea, such as Celiac disease.
  • Chronic infections : A persistent use of antibiotics or parasitic infection during travel can lead to chronic diarrhea.
  • Drug-induced diarrhea : this type of diarrhea is induced by certain laxatives and other medications or antibiotics.
  • Endocrine causes : hormonal factors also cause diarrhea, for instance, in the case of Addison disease and carcinoid tumors.
  • Neoplastic diarrhea : this type of diarrhea is linked with different forms of gut cancers.

Causes of Diarrhea:

Diarrhea may result from a variety of conditions or circumstances. The main causes of diarrhea are:

  • A food allergy or intolerance, for example: lactose intolerance
  • A medication reaction
  • A viral infection
  • A bacterial infection
  • Infection in the gastrointestinal tract
  • A parasitic infection
  • Gallbladder or stomach operation

Research studies by Mayo Clinic say that Rotavirus is a major factor that causes childhood diarrhea. Other bacterial infections caused by Salmonella or Escherichia coli, may also result in diarrhea.

Irritable bowel disorder or inflammatory bowel syndrome may also sometimes cause chronic diarrhea. If you are experiencing regular and severe diarrhea, it could mean you are suffering from a functional bowel disorder or an internal intestinal problem.

Diarrhea may have various signs or symptoms. You might get one of these or a combination of many symptoms. The symptoms occur depending on the underlying cause. Mostly, you may experience the following signs:
