What are the symptoms of zinc deficiency in adults?

The main symptoms of zinc deficiency in adults include the following aspects: 1. Digestive system symptoms: such as loss of appetite, reduced food intake, picky eating, anorexia, and even pica (craving for non-food items), as well as bloating, abdominal pain, and indigestion. This is because zinc is one of the components of gustin (a protein involved in taste function), and zinc deficiency can affect the growth of taste buds and impair taste function. 2. Skin and hair symptoms: dry, rough skin that is prone to damage, such as rashes and acne, as well as hair loss, thinning hair, and dull hair color. 3. Neurological and sensory disturbances: decreased memory, difficulty concentrating, slow reaction time, and possible impairment of taste and smell. 4. Immune system symptoms: weakened immune function, leading to frequent infections such as colds, pneumonia, and diarrhea. 5. Other symptoms: may also include vision problems, night blindness, tongue inflammation, chest tightness, shortness of breath, and palpitations. Adults with zinc deficiency should seek medical attention promptly and follow medical advice for treatment and zinc supplementation. In daily diet, attention should be paid to increasing intake of zinc-rich foods, such as oysters, lean meats, and eggs.
