People’s health problems are also changing due to busy lifestyle, mental stress and changing food. These have a common but worrying symptom-a sudden or slow decrease in appetite. If your appetite has reduced compared to before, and this condition persists for more than a few days, it can be not only a matter of digestion, but also a sign of a serious disease in the body.

Experts believe that prolonged appetite or continuous fall in appetite, may be an initial warning of many health disorders within the body. Let us know which potential diseases this symptom can be associated with.

1. Digestive system disease

Losing appetite first indicates stomach problems. A person’s appetite is also affected in gastritis, ulcers, acidity, constipation or liver disorders such as fatty liver or hepatitis. In these conditions, the stomach always feels full and the interest in food decreases.

2. Thyroid disorder

Hyperthyroidism (excess of thyroid hormones) sometimes increases the appetite, but in the event of hypothyroidism (lack of thyroid), the metabolism slows down, which makes the person feel less hungry. Along with this, weight gain, fatigue and chills are also common symptoms.

3. Mental health problems

Depression, anxiety or excessive stress directly affects appetite. Due to mental instability, the person feels faded, unnecessary or cumbersome. If the mind is feeling depressed and lack of energy with lack of appetite, then mental health check is necessary.

4. Cancer and other serious diseases

Lack of appetite can also occur at times a warning of serious diseases like cancer inside the body. This symptom is mainly seen in cancer of the stomach, liver or pancreas. Apart from this, this symptom also appears in chronic diseases like HIV, TB.

5. Diabetes and kidney disease

The imbalance of blood sugar also affects appetite. Type 2 diabetes often reduces hunger. Similarly, in kidney failure or chronic kidney disease, the demand for energy of the body decreases and the level of hunger goes down.
