Is night sweats and hair loss due to kidney yin deficiency?
In Chinese medicine, night sweats are considered to be a result of an imbalance between Yin and Yang, with a deficiency in Yin Qi and an excess in Yang Qi. This deficiency in Yin leads to internal heat, which causes the leakage of body fluids, manifesting as excessive sweating during sleep. Hair loss can have many causes, including physiological hair loss, aging-related hair loss, and hereditary hair loss, so it is not necessarily due to a deficiency in kidney Yin. However, if a person experiences both night sweats and hair loss, it is possible to first consider the presence of a kidney Yin deficiency causing these symptoms.
How to treat hypoglycemia?
First, we need to accurately identify what hypoglycemia is. We often judge the occurrence of hypoglycemia based on symptoms, such as common symptoms including palpitations, dizziness, pale complexion, general weakness, trembling limbs, sweating, etc. When these symptoms appear, we should immediately use a rapid glucose meter to measure the fingertip blood sugar. If the blood sugar is below 2.8, then the diagnosis of hypoglycemia is confirmed. We immediately provide sugary drinks or other forms of energy substances, and the symptoms of low blood sugar can be greatly relieved.
Standard for Low Blood Sugar
Our diagnostic criteria for hypoglycemia are often based on the "Whipple's triad," which is determined first by the presence of symptoms of hypoglycemia, such as palpitations, dizziness, pale complexion, cold sweats, confusion, mental abnormalities, and so on. Second, after the symptoms appear, we measure blood glucose; in non-diabetic patients, blood glucose below 2.8 mmol/L, and in diabetic patients, blood glucose below 3.9 mmol/L, then it can be judged as possibly hypoglycemia. Third, after measuring blood glucose, we quickly provide sugars, administer oral sugar water, biscuits, etc., and his symptoms of hypoglycemia quickly alleviate. Based on these three points, we can diagnose hypoglycemia.
Prevention of Gestational Diabetes
The prevention of gestational diabetes mainly focuses on diet and exercise. First, weigh yourself every morning to monitor weight changes during pregnancy, as excessive weight gain can increase the risk of gestational diabetes. Second, maintain a healthy and balanced diet that is low in fat and calories, and high in fiber and protein, avoiding excessive consumption of high-sugar foods. Third, regularly engage in exercises suitable for pregnancy. Fourth, keep a regular routine. Finally, closely monitor the fetus.
Gestational diabetes indicators
Gestational diabetes refers to the absence of a diabetes history before pregnancy, but during pregnancy screening (Tang screening), blood sugar abnormalities are discovered. At this point, the diagnosis of gestational diabetes is made. The criteria for diagnosing gestational diabetes are based on a diabetes screening test conducted at 24-28 weeks. If the fasting blood glucose is ≥5.1, one-hour blood glucose is ≥10.0, or two-hour blood glucose is ≥8.5, meeting any one of these criteria is sufficient for a gestational diabetes diagnosis.
What is hypoglycemia?
Hypoglycemia refers to a condition where the concentration of glucose in the bloodstream is too low, leading to insufficient energy supply in the body. This can excite the sympathetic nervous system or disrupt central nervous system functions, resulting in a range of clinical syndromes. Hypoglycemia is relatively common in our daily lives. Its symptoms often include palpitations, dizziness, trembling limbs, apathy, abnormal behavior, and in severe cases, even coma or sudden death. Therefore, timely diagnosis and treatment of hypoglycemia are very important.
What to eat for diabetic foot
The treatment of diabetic foot begins with good blood sugar control. Therefore, dietary control is necessary for diabetic foot. For diabetic patients, it is required to eat three meals a day at regular times and avoid multiple smaller meals or snacks. Foods such as fruits, nuts, and those high in fats should be eaten less frequently. Additionally, liquid foods like soups and porridges should also be reduced. Only when blood sugar is well-controlled can the treatment of diabetic foot be effective.
What are the symptoms of hypoglycemia?
The symptoms of hypoglycemia primarily manifest as signs of sympathetic nervous excitement and lack of oxygen in brain cells. Sympathetic nervous excitement can cause feelings of hunger, pale complexion, palpitations, dizziness, and trembling limbs. Meanwhile, the lack of oxygen in brain cells primarily presents as disturbances in neurological functions. The most common symptoms include inability to concentrate, slow speech and thought processes, drowsiness, abnormal behavior, and in severe cases, it can even lead to coma.
How to treat thyroid cysts?
Thyroid cysts refer to fluid-filled sacs found in the thyroid, generally round in shape and varying in size, with no significant clinical symptoms. They can appear as a single nodule or multiple nodules. Typically, when thyroid cysts are detected, high-resolution thyroid ultrasonography can be used to observe their ultrasonographic appearance. Thyroid cysts are generally considered benign thyroid nodules and usually do not require treatment. Regular follow-up with thyroid ultrasound is sufficient. If the thyroid cyst is too large and causes compressive symptoms, such as difficulty in breathing or swallowing, hoarseness, etc., surgical removal can be considered.
Where to do acupuncture for thyroid nodules?
Thyroid nodules do not require acupuncture treatment. The vast majority of thyroid nodules are benign, with only a small portion, about 5%, being malignant. We generally determine the treatment approach based on whether the nodule is benign or malignant. For benign nodules, we typically follow up with observation, while malignant nodules require surgical treatment and oral medication, or Iodine-131 radiotherapy. The primary evaluation for distinguishing between benign and malignant nodules relies on the results of color Doppler ultrasound and the pathology results from thyroid fine-needle aspiration.
