A person’s inability to gain weight may stem from congenital genetic factors, as individual constitutions vary. Other possible causes include spleen-stomach deficiency or a condition characterized by a relatively strong stomach but a weak spleen. When the spleen and stomach are deficient, digestion and absorption of food are impaired; consequently, the body cannot fully absorb nutrients, preventing weight gain—even with a good appetite, inadequate nutrient absorption occurs if the spleen is weak.
