Hypothyroidism refers to hypothyroidism. Patients with hypothyroidism during pregnancy should take appropriate supplements of protein and dietary fiber, as well as a low-fat diet. 1. Appropriate supplementation of protein: Eating high protein food, such as fish, beef, eggs, milk, etc., can timely replenish the body’s normal metabolic needs. 2. Appropriate dietary fiber: Eat foods containing dietary fiber, such as whole wheat flour, beans, oats, fruits and vegetables, etc., can promote gastrointestinal peristalsis, because patients with hypothyroidism are prone to bloating, constipation, and so on. 3. Low-fat diet: hypothyroidism is prone to abnormal lipid metabolism, so it is recommended to have a low-fat diet, and avoid deep-frying, pan-frying and other cooking methods. Patients with hypothyroidism during pregnancy should have a scientific diet under the guidance of a doctor.
