Multiple arteritis
Mostly in young women. Multiple Takayasu arteritis often involves multiple large and middle arteries, such as aorta, abdominal aorta, brachiocephalic artery, and upper and lower limb arteries. If it occurs in the lower limbs, the lower limbs will become cold.
Thromboangiitis obliterans
It is called “gangrene” in traditional Chinese medicine and is mostly born in middle-aged men. In the early stage, the skin of the legs and feet is cold, the skin color is pale or blue, and the pain and sour swelling during walking can be alleviated after a short rest. When the disease further develops, dry skin, muscle atrophy and pain of the affected limb will appear, especially at night. When the above symptoms occur, they should be attached great importance to, and timely go to the hospital for examination and treatment.
Reynolds phenomenon
It is often seen in middle-aged and young women, and is typically manifested in that the ends of the fingers (toes) of both hands turn white and cool after getting cold, then turn purple and red, and finally return to normal. The cause is spasm of arterioles at the end of fingers (toes). When it belongs to the primary disease, it is called “Raynaud’s disease”; If it is secondary, it is called “Reynolds phenomenon”. Diseases causing Raynaud’s phenomenon include scleroderma, dermatomyositis, lupus erythematosus, thromboangiitis obliterans, and polyarteritis nodosa.
Hand and foot cold
In addition to the above symptoms, generally speaking, people have cold hands and feet, which may be due to “hand and foot cold”. Women account for the majority of the people with cold hands and feet. This is because hormone changes caused by menstruation and childbirth will have a certain impact on the autonomic nervous system, and this sensitivity of the autonomic nervous system will lead to the contraction of subcutaneous blood vessels and the reduction of blood flow, which will lead to cold. Menopausal women over 40 years old with insufficient estrogen, postpartum mothers or patients with cardiac dysfunction, hypothyroidism, malnutrition, anemia, hypotension and pelvic inflammation generally have symptoms of cold hands and feet.
Psychological problems
People with excessive mental pressure, excessive psychological sensitivity, excessive worry and constant anxiety are also high-risk people of hand and foot colds. In this case, you should first calm down and then receive medical treatment. People with cold hands and feet should improve their living habits and strengthen physical exercise. Especially those who sit or stand for a long time must pay attention to inter work exercises and do more hand, foot and waist activities to strengthen blood circulation. Take more vitamins B1 and B12. Eating beef bone soup, beef liver, beans, milk and other foods rich in iron and vitamin F can also help improve symptoms.
