A poor appetite may be due to stress, illness, digestive problems, infections, certain medicines, or nutritional deficiencies. The first step is to improve daily habits. Try eating small but frequent meals instead of large portions. Include foods that are easy to digest and rich in nutrients, such as fruits, vegetables, eggs, milk, lentils, and soups. Regular light exercise, such as walking, can also help improve hunger. Make sure you drink enough water, but avoid drinking too much just before meals, as it can reduce appetite. Eating at regular times every day and making meals more enjoyable with variety can also help. If the problem persists, consult a doctor to check for any underlying causes. In some cases, medicines may be prescribed, such as cyproheptadine or certain antidepressants like mirtazapine, but these should only be taken under medical supervision. Vitamin and mineral supplements, especially zinc and B vitamins, may also help if there is a deficiency. Avoid self-medication and seek proper medical advice for safe treatment.
