In winter, the feet are like ice cubes, and many people have this experience. However, some cold legs and feet may be a problem with blood vessels.
Cold legs and feet. It may be that the blood vessel is "blocked".
The First Affiliated Hospital of Zhejiang University School of Medicine shared a case in *** on December 6, 36-year-old Mr. Wu (pseudonym) has been cold in his legs and feet since the beginning of winter, no matter how he covers it, he can't get hot, and gradually develops pain symptoms, especially when he walks with his right foot, he hurts badly and walks with a little limp. After a series of examinations at the hospital, it turned out that the blood vessel was blocked!
Zhu Qianqian, deputy chief physician of the Department of Vascular Surgery of the First Affiliated Hospital of Zhejiang University School of Medicine, said that although Mr. Wu is not very old, he has developed arteriosclerosis, and the rupture of arteriosclerotic plaque has secondary thrombosis, resulting in a very firm blockage of the artery in his right foot. ①

These symptoms appear.
It may be that the blood vessels are "calling for help".
If you have cold legs and feet, beware!Don't think it's just the weather, it may also be that the blood vessels have been blocked, and if you don't do it in time, you may have to amputate it in serious cases. There are two main conditions of blockage of blood vessels in the lower limbs, arteriosclerosis occlusion of the lower limbs and deep vein thrombosis of the lower limbs.
Jin Yongjian, chief physician of the Third Department of Neurosurgery of the Aviation General Hospital, said in an article in the Health Times in 2019 that the blockage of blood vessels is not an overnight thing, but a gradual accumulation over time. To prevent blood clots, you need to pay attention to these signals sent by your body. ②
1.Numbness in the legs.
When there is a blood clot in the human blood, the limbs will feel numb and painful due to insufficient blood supply. Therefore, if you suddenly feel leg pain, pressure or numbness in your lower limbs, you must be vigilant.
2.Walking with a limp.
If the blockage of the blood vessels worsens, intermittent claudication occurs. After walking a few hundred meters, you will feel soreness in your legs, and you need to rest for a while to relieve it. Blood clots can cause a lack of blood supply, leading to muscle soreness. If you ignore the blockage of the arteries of the lower limbs, the disease will progress further, which may lead to severe ischemia of the lower limbs, the temperature will drop, the pulse of the dorsum of the foot and the posterior tibial artery will weaken or disappear, and the lower limbs will have pain when not walking, and further development may cause limb rupture, wounds that cannot heal, and even tissue necrosis.
3.Thickening of the legs.
Blood clots form in the veins, blood cannot flow back to the heart, and the pressure causes fluid to spread to the leg tissues, most easily recognizable as a sudden unilateral leg swelling, usually below the knee. If you feel swelling in your lower legs but can't be sure by visual inspection, you can use a tape measure to measure the comparison.
A way to teach you to identify blood clots!
Tong Mingxiao, a nurse in charge of the nursing department of Beijing Jishuitan Hospital, said in an interview with the Health Times in 2016 that a good way to self-check for deep vein thrombosis at home is to measure leg circumference.
The measurement method is: 15 cm above the patella, 10 cm below the patella, respectively, after the measurement of the two legs contrast, if one leg is more than 1 cm more swollen than the other, it means that there is a problem. If both legs are swollen together, measure 23 cm today, and measure all 25 cm tomorrow. In addition to drinking too much water, less urine, or other symptoms, it is important to consider that there is a risk of deep vein thrombosis in the lower extremities and that you should seek medical attention as soon as possible. ③
Drinking 5 glasses of water can prevent blood clots.
1st cup of water: after waking up.
Xia Pengbin, a dietitian from the Department of Clinical Nutrition of Zhongda Hospital Affiliated to Southeast University, said in an article in Health Times in 2018 that morning is the time when the physiological blood pressure of the human body rises, platelet activity increases, and blood viscosity increases. Drinking water after waking up can help reduce blood viscosity, which reduces the risk of blood clots. Warm plain water is the best option.
2nd cup of water: before morning exercise.
Many people are Xi to drinking water after morning exercise, and should drink a small amount of water before morning exercise to reduce the risk of dehydration and blood viscosity caused by exercise, and help prevent blood clots. Drink water not too quickly, in small amounts and many times.
3rd cup of water: half an hour after meals.
Do not drink water immediately after meals, otherwise it will dilute and dilute saliva and gastric juice, affecting digestion and absorption. Drinking water half an hour after eating, about 200 ml, helps to alleviate the increase in blood viscosity after meals. But drink it in small sips, otherwise drinking water frequently and in large quantities is easy to burn.
4th glass of water: before leaving work.
Office workers often neglect to drink water because they are busy, which provides an opportunity for blood clot invasion. It is recommended that office workers develop the Xi of drinking a few sips of water before getting off work, the amount of a paper cup is enough, don't drink too much, otherwise it is easy to "urinate" on the way off work.
5th cup of water: before going to bed.
Take two sips of water before going to bed. When a person is asleep, water is lost in the body, causing the blood to become more viscous. Drinking some water before going to bed can alleviate this phenomenon and reduce the risk of cerebral thrombosis. In addition, it is best for the elderly to always have a glass of water by the bedside before going to bed and take a few sips when they feel thirsty. ④
