TSH refers to thyroid stimulating hormone. Elevated thyroid stimulating hormone can be seen in subclinical hypothyroidism, hypothyroidism, etc. Maintaining a low-fat, high-fiber diet is sufficient. Elevated thyroid stimulating hormone with decreased thyroid hormone is considered to be hypothyroidism, while elevated thyroid stimulating hormone alone is considered to be subclinical hypothyroidism. Hypothyroidism or subclinical hypothyroidism may cause constipation and elevated blood lipids, etc. It is necessary to maintain a low-fat, high-fiber diet, avoiding high-fat foods such as fried foods and fatty meats, and increasing the intake of high-fiber foods such as corn, oats, and vegetables and fruits as appropriate. When TSH is elevated, it is recommended to go to the hospital and ask the doctor to make a judgment.
