Thin Endometrium

Thin endometrium refers to an endometrial thickness below the normal level (usually <7mm), commonly seen in women of reproductive age, particularly in those with multiple abortions or hormonal imbalances. Globally, higher incidence rates are reported in developed countries such as the United States and Japan, as well as Southeast Asian countries including Indonesia and the Philippines. This condition may cause infertility, recurrent miscarriage, and significantly affect women’s reproductive health.

In Southeast Asia, the incidence of thin endometrium is rising, associated with factors such as environmental pollution and increased stress. Countries like Thailand and Malaysia report a higher number of cases, with risks including pregnancy failure and reduced IVF success rates. Early intervention can improve prognosis and increase fertility chances.

Detailed Symptoms of Thin Endometrium

1. Reduced Menstrual Flow

Patients with thin endometrium often experience significantly lighter periods, sometimes just spotting. Due to the thinner endometrium, less tissue is shed. While cycles may remain regular, periods are shorter with lighter color and flow.

2. Infertility or Recurrent Miscarriage

A thin endometrium cannot provide sufficient nutrition and implantation environment for the embryo, leading to infertility or early miscarriage. Even if pregnancy occurs, risks of embryo arrest or biochemical pregnancy remain high.

3. Irregular Menstrual Cycles

Some patients may have irregular cycles, with periods delayed or early, sometimes accompanied by dysmenorrhea. Hormonal imbalance is one of the main causes.

4. Vaginal Dryness

Thin endometrium is often associated with low estrogen levels, leading to decreased vaginal secretions, dryness, and discomfort or pain during intercourse.

5. Lower Back Pain and Fatigue

Some patients experience lumbosacral pain or general fatigue, possibly linked to blood deficiency or endocrine disorders.

6. Pale or Dull Complexion

Patients with blood deficiency often show pale or dull complexion, sometimes with melasma, reflecting abnormal hormonal and nutritional status.

7. Emotional Instability

Low estrogen levels may trigger mood swings, anxiety, or depression, affecting quality of life.

8. IVF Failure

Patients with thin endometrium undergoing IVF often face low implantation rates and significantly increased risk of multiple failed embryo transfers.

9. Lower Abdominal Pain

Some patients present with non-cyclical lower abdominal pain, possibly related to poor pelvic blood circulation or inflammation.

Conclusion

Experts at United Life International Medical Center remind that thin endometrium requires early intervention to prevent infertility or miscarriage. New technologies such as stem cell therapy can promote endometrial repair and improve pregnancy success rates. Regular check-ups combined with individualized treatment plans are recommended to improve reproductive outcomes.
