**** Reasons for unexplained weight loss.

There are several reasons for losing weight, some of which are physical, and sometimes psychological, and the most important reasons for unjustified weight loss include the following:

1. Cancer

Often, other symptoms associated with the disease may appear before weight loss occurs, and these symptoms vary depending on the location and type of the tumor.

So weight loss may be the most obvious symptom, as in cases of stomach cancer, esophageal cancer, or pancreatic cancer.

2. Hyperthyroidism

Although this disease is associated with many symptoms, such as excessive sweating, rapid heartbeat, sleep problems, and excessive nervousness, in the initial stages, these symptoms may not seem obvious, and weight loss appears without justification.

3. Anxiety and depression

Anxiety and depression are among the reasons for unjustified weight loss, as people with psychological problems tend to stay away from food most of the time as a result of loss of appetite.

Some sufferers also resort to relieving their anxiety by excessive smoking, which increases the loss of appetite due to the nicotine contained in cigarettes.

4. Malabsorption syndrome

Infection with some diseases leads to problems absorbing nutrients inside the intestines, which leads to several symptoms, including weight loss, and these diseases include the following:

Digestion dysfunction.

Ulcerative colitis.

Peptic ulcer.

Crohn's disease.

5. Side effects of some medicines

Taking some medications can lead to dry throat, loss of appetite and heartburn, leading to discomfort, a change in eating habits and the possibility of weight loss.

6. Other reasons for unexplained weight loss

In addition to the above reasons for unjustified weight loss, there are other reasons as follows:


Some types of viral, bacterial, or parasite infections, such as: AIDS or tuberculosis.

Alcoholism or drug abuse.

Excessive intake of laxatives.

Diseases related to difficulty swallowing.


Eating disorders, such as: bulimia or anorexia.

Unexplained weight loss treatment

Treatment is often aimed at preventing or preventing the patient from losing more weight, by following a special diet as part of a strategy to increase food intake.
