Introduction

In general, being sensitive to cold may be caused by factors such as aging, poor physical condition, anemia, common cold, or hypothyroidism. If you experience any discomfort, seek medical attention immediately. In daily life, you should engage in appropriate physical activities, such as walking, jogging, swimming, etc., which can help promote blood circulation and thereby improve cold sensitivity.

Generally, being sensitive to cold may be caused by aging, poor constitution, anemia, common cold, hypothyroidism, and other factors. It is recommended to seek timely medical consultation to identify the specific cause and receive appropriate treatment. Detailed explanations are as follows:

1. Aging

With increasing age, bodily tissues and organ functions gradually decline, and metabolism slows down, resulting in reduced body heat production, thus making the body more prone to feeling cold. It is recommended to maintain warmth in daily life by wearing suitable clothing, especially thermal undergarments, down jackets, etc.

2. Poor Constitution

A poor constitution may result from various factors such as low body fat and improper diet. Individuals with poor constitution typically have lower immunity and reduced ability to retain body heat, leading to heat loss and the aforementioned symptoms. It is advisable to maintain a balanced and healthy diet, consume adequate protein and vegetables, exercise regularly, and improve immunity.

3. Anemia

Anemia may be caused by malnutrition, dietary habits, and other factors. Anemia can reduce the blood's capacity to carry oxygen due to decreased hemoglobin levels, causing cold sensations in peripheral body parts due to oxygen deficiency. Other symptoms such as fatigue and weakness may also appear. Patients can take medications such as ferrous sulfate tablets, polysaccharide iron complex capsules, or Ejiao Buxue Granules as advised by a physician.

4. Common Cold

A common cold may be caused by bacterial or viral infections. When a person has a cold, the body's temperature regulation center may be affected by the immune system, leading to impaired temperature regulation and a feeling of coldness. Symptoms such as nasal congestion, runny nose, and cough may also occur. Patients can take medications such as ribavirin granules, ganciclovir tablets, or paracetamol tablets under medical guidance to alleviate discomfort.

5. Hypothyroidism

Hypothyroidism may be caused by iodine deficiency, thyroid dysfunction, or other reasons. Reduced secretion of thyroid hormones slows metabolism and decreases body heat production, leading to cold intolerance. Symptoms such as weight gain and memory decline may also occur. Patients can take medications such as levothyroxine sodium tablets, vitamin D3, or thyroid extract tablets as directed by a physician.

In daily life, it is also recommended to engage in moderate physical activities such as walking, jogging, or swimming, which can help promote blood circulation and improve cold sensitivity.

What are the late-stage symptoms of breast cancer metastasized to the liver?

When breast cancer cells spread to the liver and reach the terminal stage, patients often develop typical symptoms such as persistent upper right abdominal distension and pain, jaundice throughout the body, severe abdominal bloating resembling a drum, rapid weight loss, and marked loss of appetite. These symptoms indicate severe liver dysfunction and necessitate prompt systemic intervention at a specialized oncology center. In the terminal phase, liver function, coagulation, and blood ammonia levels should be monitored weekly, and animal protein intake should be restricted to prevent hepatic encephalopathy.
