How is the nail purple?

Hello, your symptoms may be as follows.

One. The tips of human limbs, that is, toes and hands, are far from the heart and have weak blood supply ability. In winter, the heat at the fingertips is lost and the blood cannot be supplied quickly, so the temperature at the fingertips will be low, the capillaries will contract, the blood flow will not be smooth, the venous blood will not return immediately, and the arterial blood will not be supplied immediately, and the nails will turn purple. In severe cases, nails will be frostbitten.

Two. Pay attention to check whether hemoglobin is abnormal.

Three. Congestion performance, temperature rise accelerates blood circulation and naturally restores its true color.

Four. Abnormal cardiopulmonary function.

Suggestion: Pay attention to nutrition during weight loss and don't go on an excessive diet. The weather is unstable, please keep warm. If you do a lot of exercise, you should pay attention to your body's adaptability and don't force it.

I wish you success in losing weight and getting your nails back to normal. If the symptoms are too severe or cannot be recovered for a long time, please go to the hospital for examination.
