These five "foot phases" hide systemic diseases.
Big toe suddenly becomes "fat": beware of gout
If this symptom suddenly attacks and gets better after a while, it is probably gout. If the elderly have this symptom, accompanied by hallux valgus, and the symptoms persist, it may be hallux valgus.
Yellow toenails: beware of fungal infection
The onychomycosis caused by fungal infection may appear thick and yellow toenails, and may spread to all toenails and even fingernails, emitting an unpleasant smell and darkening the color. Diabetic patients, people with circulatory disorders and people with low immune function are easily infected with this disease.
Foot numbness: check blood sugar
Besides excessive walking, osteopenia, malnutrition and vitamin D deficiency, it may also be a manifestation of type 2 diabetes. Among them, the pain is mostly burning, and the numbness is like wearing socks. It is best to go to the endocrinology department in time to find out the cause.
Cold soles: check thyroid gland.
Generally speaking, women's basal body temperature is slightly lower than that of men, and they often feel cold at the ends of their limbs. Many lower extremity vascular diseases and neuropathy can also cause cold feet. In addition, the thyroid gland is an organ that regulates metabolism and body temperature. When hypothyroidism occurs, the limbs will feel cold. If women over 40 years old have cold feet for a long time, it may be caused by insufficient thyroid function and need to seek medical attention in time.
Heel pain: it may be an ankle disease.
Foot and ankle diseases not only have congenital developmental problems, such as high arch foot, flat foot and hallux valgus, but also have symptoms caused by chronic strain, among which heel pain and plantar fasciitis are the most common. It can be said that more than 90% of middle-aged and elderly people and many young people have these two kinds of foot problems, and young people have more and more heel pain. Heel pain is mostly caused by bone spurs and sports strain. , but also related to wearing thin shoes, high heels, platform shoes, snow boots, etc.
How to implement foot health care?
1, keep your feet warm and prevent stomachache.
Chinese medicine believes that "cold starts from the first step, and disease starts from cold". The foot is far from the heart, the blood flow is small, and the temperature of the foot surface is lower than that of the body. Once you get cold and freeze, it will affect the operation of qi and blood. Poor blood circulation will not only damage the skin, but also cause stomach pain, low back pain, dysmenorrhea and other diseases. This is the truth of "raising trees to protect roots, raising people to protect feet".
It is recommended to keep your feet warm to avoid being blown by cold wind, and it is best to wear rain boots when it rains. Even in summer, the elderly should try to wear a pair of thin cotton socks or breathable cotton socks to build a "barrier" between the skin and shoes to avoid cold feet.
2. Wear suitable shoes to protect the spine
Improper sandals, flip-flops, high heels, etc. Will lead to foot deformation, will produce a sense of human internal organs. For example, squeezing the thumb due to improper shoes may affect the function of the human head; The deformity of the medial thumb may also damage the spine and affect the thyroid function of human body. It is recommended to wear soft, comfortable and breathable sports shoes and soft-soled shoes, or prepare a pair of soft-soled slippers in the office.
Women should choose high heels with different heights to avoid squeezing the same ankle frequently; It is best to choose high-heeled shoes with wide toes and heel height less than 5 cm to avoid hallux valgus (bone bulge formed at the root of the big toe) when the big toe is caught in a narrow space.
3. Adjust posture to relieve ankle problems.
"Low-headed people" should stand up and rest for 65,438+00 minutes every 45 minutes, stretch and make a passive backward neck, which can alleviate ankle problems caused by poor posture, such as holding their heads with both hands, pushing forward with both hands, and leaning back for a few seconds at the same time, in groups of 65,438+00, five groups a day. A good sitting posture is to sit at 1/3 of the chair, hold your chest out and exert your back muscles.
In addition, adjusting body posture can also protect ankles. It is suggested to adopt "wall-sticking training": stick your head, hips and heels on the wall at 3 o'clock (shoulder blades are better on the wall at 5 o'clock), look straight ahead, relax your shoulders and arms, and look in the mirror to see if your shoulders are horizontal.
Practice from a few minutes every day, and gradually increase it to 20~30 minutes. If possible, do it once in the morning and evening, and let the brain find the correct "balance posture". It is best to stand barefoot, or wear low-heeled flat shoes or thick socks.
