Cold feet in winter

Generally speaking, patients with anemia and gastrointestinal diseases, those with nutritional deficiencies or those with hypothyroidism that cause systemic or local poor blood circulation, or impaired blood circulation at the limbs, can cause cold hands and feet. In particular, women's menstrual periods, pregnancy and childbirth, are more likely to cause cold hands and feet due to physical weakness. In medicine, often cold and cold hands and feet can be called "cold cold".
