Significant decrease in ghrelin (hunger) hormone levels affects appetite. Also, some other factors can affect it:

  • Vitamin deficiency
  • Mineral deficiency
  • Thyroid hormones
  • Psychological factors
  • Cigarette
  • Skipping meals
  • Low water intake

If you have a poor appetite,

  • Check your vitamins, minerals, and thyroid hormones regularly, consult your doctor, and use the medications your doctor recommends.
  • Check your psychological state (grief, nervousness, stress, tension, etc.). If you can't handle these situations, get psychological support.
  • Smoking cigarette creates effects sensitivity to smell of food and drinks, so they become disgusting.
  • Don't skip your meals. The shrinking stomach empties much faster than a normal stomach. Food intake is made more difficult by the sensitivity of the stomach. When your stomach is empty for a long time, you may experience constipation.
  • If you are starved long time, your ghrelin (hunger) hormone increases constantly. If you take your snacks and main meals regularly, your stomach does not stay empty for a long time, so it can take the food; the next time you eat, it would be easier.
