What causes cold sensitivity in early pregnancy?

Generally, feeling cold during early pregnancy may be caused by hormonal changes, circulatory changes, anemia, endocrine disorders, hypothyroidism, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific explanations are as follows:

1. Hormonal influence: During early pregnancy, hormone levels in a pregnant woman's body typically change, often resulting in increased progesterone secretion. Progesterone may cause blood vessel dilation, leading to greater heat loss, which can make the expectant mother feel cold. This is a normal physiological phenomenon. Symptoms can be alleviated by wearing warm clothing and adjusting indoor temperatures.

2. Circulatory changes: Blood volume usually increases during pregnancy, which may lead to insufficient blood supply to the extremities, causing the hands and feet to feel cold. Pregnant women can try light physical activities such as walking or yoga to help improve circulation.

3. Anemia: This may be related to inadequate vitamin intake or folic acid deficiency. Anemia reduces the blood’s ability to carry oxygen, leading to tissue hypoxia and a sensation of coldness. It may also be accompanied by symptoms such as dizziness and fatigue. Pregnant women should follow medical advice to take medications such as ferrous lactate oral solution, folic acid tablets, or ferrous gluconate syrup to improve their condition.

4. Endocrine disorders: These may result from fluctuations in hormone levels or changes in living environment. Endocrine imbalances can affect metabolism and body temperature regulation, leading to cold sensitivity. Other symptoms may include mood swings and weight changes. As directed by a physician, medications such as Wuji Baifeng Pills, Jingxin Oral Liquid, or Yimucao Granules may be prescribed for improvement.

5. Hypothyroidism: This may be caused by pituitary changes or prolonged iodine deficiency. The condition typically slows down the body's metabolic rate, reducing heat production and making the pregnant woman feel cold. Additional symptoms may include fatigue, constipation, and weight gain. Treatment under a doctor’s supervision may include medications such as levothyroxine sodium tablets, thyroid tablets, or alfacalcidol soft capsules.

In daily life, it is recommended that pregnant women soak their feet before bedtime and consume warming foods such as brown sugar and ginger soup. Avoiding prolonged exposure to cold environments can also help alleviate feelings of coldness.
