What are the symptoms of hypothyroidism and what should I pay attention to in my diet? Hypothyroidism, or hypothyroidism for short, is a syndrome caused by insufficient synthesis, secretion or biological effects of thyroid hormones. The cause of hypothyroidism is complex, with primary hypothyroidism being the most common, followed by pituitary hypothyroidism, and others being rare. Patients may have symptoms such as weakness of limbs, endocrine hypocrisy, hypotension, vertigo, myasthenia gravis, abnormal body shape and abnormal breathing. Manifestations and Diagnosis 1. Color problems: pale face, eyes, face and cheeks are deficient and swollen, apathetic expression, dementia, dry, thickened, rough and flaky skin all over the body, non-sunken edema, hair loss, palms of hands and feet are shriveled and yellowish in color, weight gain, and a few patients have thick and brittle fingernails. 2.Neuropsychiatric system: memory loss, mental retardation, drowsiness, slow reaction, anxiety, dizziness, headache, tinnitus, deafness, nystagmus, ataxia, tendon reflexes, Achilles tendon reflexes prolonged, dementia can occur in the severe cases, stiffness, and even lethargy. 3, cardiovascular system: bradycardia, reduced cardiac output, low blood pressure, low heart sound, heart enlargement, can be complicated by coronary artery disease, but generally do not occur angina pectoris and heart failure, sometimes accompanied by pericardial effusion and pleural effusion. Mucous edema cardiomyopathy occurs in severe cases. 4, digestive system: anorexia, abdominal distension, constipation. In severe cases, paralytic intestinal obstruction may occur. Gallbladder contraction is weakened and distended. Half of the patients have gastric acid deficiency, leading to pernicious anemia and iron deficiency anemia. 5, motor system: muscle weakness, pain, ankylosis, can be accompanied by joint lesions such as chronic arthritis. 6, endocrine system: female menorrhagia, amenorrhea, infertility; male impotence, loss of libido. A few patients appear lactation, secondary pituitary enlargement. 7, when the condition is serious, due to cold, infection, surgery, anesthesia or sedative application of improper stress can be induced by mucous edema coma. The manifestation of low body temperature (T < 35 ℃), respiratory slowing, bradycardia, blood pressure drops, limb muscle relaxation, reflexes weakened or disappeared, and even coma, shock, cardiac and renal failure. 8.Dull small disease: dull expression, mute pronunciation, pale face, periorbital swelling, widening of the distance between the eyes, nasal bridge collapse, thick salivation lips, tongue large outstretched limbs short, duck step. 9, juvenile hypothyroidism: short stature, low intelligence, delayed sexual development. Diet 1, dietary iodine in the right amount. 2, the supply of adequate protein: the amount of protein per person per day at least more than 20G, in order to maintain the human body protein balance egg, amino acids are the basic components of the composition of proteins, about 3% of the protein is constantly updated every day, hypothyroidism when the small intestinal mucosal renewal slowed down, the digestive secretion glands affected, enzyme vitality decreased, the general decline in albumin, so it should be supplemented with essential amino acids, the supply of adequate protein, to improve the condition. 3.Limit fat and cholesterol-rich diet: patients with hypothyroidism often have hyperlipidemia, which is more obvious in primary hypothyroidism, so it is necessary to limit fat diet. Daily fat supply accounts for about 20% of the total calories, and limit the cholesterol-rich diet. 4, correct anemia, supply rich vitamins: anemia should be supplemented with iron-rich diet, supplemental vitamin B12, such as animal liver, if necessary, but also supply folic acid, liver preparations. 5, dietary preparation: (1) appropriate food: due to iodine deficiency caused by hypothyroidism, need to choose the right amount of kelp, seaweed, available iodized salt, iodized soy sauce, iodized eggs and bread iodized. When frying vegetables, it should be noted that iodized salt wood should be put into the boiling oil to avoid iodine volatilization and reduce iodine concentration. Protein supplementation can choose eggs, dairy, all kinds of meat, fish; plant protein can be complementary, such as a variety of soybean products, soybeans and so on. Supply of animal liver can correct anemia, but also to ensure the supply of a variety of vegetables and fresh fruit. (2) Avoid selecting food: avoid cholesterol-rich food, such as cream, animal brain and offal. Limit the use of high-fat foods, such as cooking oil, peanut rice, walnuts, almonds, sesame paste, ham, pork, sweet cheese.
