2022-04-12 00:00:00

Loss of appetite is a type of eating disorder in which there is a reduced desire to eat. It can also be referred to as poor appetite or decreased appetite. The medical term for this condition is anorexia. Anorexia is an eating disorder characterized by an unusual fear of gaining weight, where people who are affected by hunger severely limit the amount of food they eat to prevent weight gain.

The exact cause of this condition is unknown but sometimes it can occur with conditions that affect the digestive system, such as infection, dehydration, or chronic diseases.

Dietary restrictions can cause nutritional deficiency, which severely affects the overall health of an individual and can further result in life-threatening complications, so it's important to find the cause and treat the condition.

Causes of Anorexia

  • Depression-

Loss of appetite can be a symptom of depression, along with other symptoms such as low mood, poor concentration, and troubled sleep.

  • Infection-

These include short-term infections (such as flu, cold, urinary tract infection, chest infection, pelvic infection, etc.) and long-term infections such as tuberculosis (TB) or HIV. All these conditions can lead to loss of appetite.

  • Stress and anxiety-

Anxiety and stress can cause digestive problems such as nausea and upset stomach. These can be so uncomfortable that it reduces the desire to eat.

  • Medication-

Many medicines can cause loss of appetite as a side effect, including some antidepressants such as methylphenidate for ADHD(Attention-deficit/hyperactivity disorder), fluoxetine, chemotherapy, some medicines for type 2 diabetes, and strong painkillers (Opioids).

  • Age-

Appetite decreases with age and this may be due to the stomach emptying (process in which the stomach contents are moved into the duodenum) which comparatively becomes slower in older age, so older people can feel full for a longer time.

  • Long-term (chronic) health conditions-

Chronic kidney disease, chronic pain, chronic liver disease and dementia.

  • Cancer-

Many cancer treatments can cause loss of appetitewhich is usually accompanied by other symptoms that are specific to particular cancer, but sometimes loss of appetite can be an early symptom of cancer.

  • Gallstones-

These can cause severe pain, especially after eating fatty foodsbecause of which the patient loses the desire to eat.

  • Oral and dental problems-

Any problem that makes it difficult for you to chew, swallow, or taste food can affect your appetite. For example, toothache, ill-fitting dentures, cavities, dry mouth, jaw dysfunction, or loss of taste.

  • Hypothyroidism-

Hypothyroidism is an underactive thyroid, which means it doesn't produce enough thyroid hormone. This slows down many of your body's functions, which can lead to a decreased appetite.
