These four changes in women indicate an estrogen imbalance. The body desperately needs estrogen, especially for women trying to conceive. A lack of estrogen during this period can make conception difficult. What are the signs of an estrogen imbalance? 1. Hot flashes. A lack of estrogen can cause hot flashes, where heat involuntarily rises from the chest to the lower limbs without any apparent reason. This may be accompanied by palpitations and sweating. Some women with estrogen deficiency may also experience hot flashes at night, waking up in the middle of the night with profuse sweating. 2. Heart palpitations. A lack of estrogen can also easily cause heart palpitations, a symptom that is common during menopause and often appears unexpectedly. These symptoms usually subside after a while, which is unexplained and cannot be detected by an electrocardiogram (ECG). This is also a sign of estrogen deficiency. 3. Abnormal mental state. Women with low estrogen levels are prone to symptoms such as frequent crying, fatigue, and irritability. Some may also experience a crawling sensation on their skin, like ants crawling all over their body, but medical examinations may not reveal any abnormalities. 4. Lower back pain. While lower back pain is common during menstruation and menopause, these symptoms are normal. However, if these symptoms occur frequently at other times, it could indicate osteoporosis, requiring timely bone health supplementation to prevent the condition from worsening. To improve estrogen levels, it's important to pay attention to daily life. Eat plenty of high-protein, low-fat foods and consume adequate fruit daily to ensure sufficient nutrition and hydration. This will also improve skin health and have beautifying effects. Try to avoid smoking, and limit alcohol and coffee consumption. Choose cooking oils that are primarily vegetable oils. Eat less or no foods high in cholesterol and saturated fatty acids, and eat more soy products such as tofu pudding, soy milk, and tofu. These foods are very high in protein and low in calories. Family members should also offer encouragement and avoid putting too much pressure on women with hormonal imbalances. Women with hormonal imbalances should also learn to relax and engage in regular physical exercise. This not only strengthens the body's resistance but also indirectly relieves stress.
