What Are the Symptoms of Low Estrogen in Women and How Are They Treated?

Why does your estrogen level matter?

Estrogen is a hormone. Although present in the body in small amounts, hormones have big roles in maintaining your health.

Estrogen is commonly associated with the female body. Men also produce estrogen, but women produce it in higher levels.

The hormone estrogen:

  • is responsible for the sexual development of girls when they reach puberty
  • controls the growth of the uterine lining during the menstrual cycle and at the beginning of a pregnancy
  • causes breast changes in teenagers and women who are pregnant
  • is involved in bone and cholesterol metabolism
  • regulates food intake, body weight, glucose metabolism, and insulin sensitivity

Girls who haven’t reached puberty and women approaching menopause are most likely to experience low estrogen. Still, women of all ages can develop low estrogen.

You may also find that your bones fracture or break more easily. This may be due to a decrease in bone density. Estrogen works in conjunction with calcium, vitamin D, and other minerals to keep bones strong. If your estrogen levels are low, you may experience decreased bone density.

If left untreated, low estrogen can lead to infertility in women.

Treatment

How is low estrogen treated?

Women who have low levels of estrogen may benefit from hormonal treatment.

Estrogen therapy

Women between the ages of 25 to 50 who are estrogen deficient are generally prescribed a high dose of estrogen. This can reduce the risk of bone loss, cardiovascular disease, and other hormonal imbalances.

The actual dose will depend on the severity of the condition and the method of application. Estrogen can be administered:

  • orally
  • topically
  • vaginally
  • via injection

In some cases, long-term treatment may be needed even after your estrogen levels return to normal. This may require lower doses of administered estrogen over time in order to sustain your current level.

Estrogen therapy may also ease the severity of menopausal symptoms and reduce your risk of fractures.

Long-term estrogen therapy is primarily recommended for women who are approaching menopause and have also had a hysterectomy. In all other cases, estrogen therapy is only recommended for one to two years. This is because estrogen therapy may increase your risk of cancer.

Hormone replacement therapy (HRT)

HRT is used to augment your body’s natural hormone levels. Your doctor may recommend HRT if you’re approaching menopause. Menopause causes your estrogen and progesterone levels to significantly decrease. HRT can help return these levels to normal.

In this therapy, hormones can be administered:

  • topically
  • orally
  • vaginally
  • via injection

HRT treatments can be adjusted in dosage, length, and the combination of hormones. For example, depending on the diagnosis, progesterone is often used in conjunction with estrogen.

Women approaching menopause who undergo HRT may have an increased risk of cardiovascular disease. The treatment has also been shown to increase your risk of blood clotting, stroke, and breast cancer.

Weight gain

Low estrogen levels and weight gain: Is there a connection?

Sex hormones, such as estrogen, influence the amount of fat in the body. Estrogen regulates glucose and lipid metabolism. If your estrogen levels are low, it can result in weight gain.

Research suggests that this may be why women approaching menopause are likely to become overweight. Being overweight can increase your risk of obesity, diabetes, and cardiovascular disease.

If your estrogen levels are low and it’s affecting your weight, consult your doctor. They can assess your symptoms and advise you on next steps. It’s always a good idea to eat a balanced diet and exercise regularly. Talk with your doctor about developing a diet and exercise plan that’s right for you.

Treatments have evolved over the years and become more effective. Your individual reason for low estrogen will determine your particular treatment, as well as the dosage and duration.
