Appetite Loss; Causes, Symptoms, Diagnosis, Treatment

Appetite loss is the desire to eat food, sometimes due to hunger. Appealing foods can stimulate appetite even when hunger is absent, although appetite can be greatly reduced by satiety. Appetite exists in all higher life-forms and serves to regulate adequate energy intake to maintain metabolic needs. It is regulated by a close interplay between the digestive tract, adipose tissue, and the brain. Appetite has a relationship with every individual’s behavior. Appetitive behavior also known as approach behavior, and consummatory behaviors, are the only processes that involve energy intake, whereas all other behaviors affect the release of energy. When stressed, appetite levels may increase and result in an increase of food intake. Decreased desire to eat is termed anorexia, while polyphagia (or “hyperphagia”) is increased eating. Dysregulation of appetite contributes to anorexia nervosa, bulimia nervosa, cachexia, overeating, and binge eating disorder.

Diagnosis of Appetite Loss

Treatment of Appetite Loss

  • Megestrol acetate or medroxyprogesterone –  which are forms of the progesterone hormone that can improve appetite and weight gain.
  • Steroid medications – which can increase appetite, improve a person’s sense of well-being, and help with nausea, weakness, or pain.
  • Metoclopramide  – which helps move food out of the stomach and can prevent feeling full before eating enough food.
  • Dronabinol – a cannabinoid made in the laboratory, which may stimulate appetite.
  • Olanzapine  – seems to promote weight gain as well as the ability to ameliorate obsessional behaviors concerning weight gain. zinc supplements have been shown to be helpful, and cortisol is also being investigated.
  • Green Eating – If you can, eat some kale, collards, or arugula. They promote the body to make more digestive enzymes and increase appetite.
  • Water – It is especially important to drink water when you have a little appetite so that you’re not battling dehydration on top of everything else. But water can also help speed up your digestive system if a slow system is a reason for not wanting to eat.
  • Spices – Both fennel and caraway can be used to aid in digestion and boost appetite. Try adding some to water or food. This is a treatment designed to fight recurring decreased appetite.
  • Exercise – Don’t go all out but take a quick stroll through the neighborhood or put in some time on the treadmill. If you can speed up your body’s energy use, your appetite should return.

  • Do not limit how much you eat.
  • Determine which times of day you are hungry and eat at those times.

  • Keep your favorite foods on hand for snacking.
  • Increase the calories and protein in foods by adding sauces, gravy, butter, cheese, sour cream, half and half, whipped cream, and nuts or nut butter.
