Early menopause affects a significant proportion of women, with long-term health implications. Recent studies show that women who experience early menopause have a significantly increased risk of suffering from coronary heart disease.
The results of a study published in JAMA Cardiology reveal that indeed women who experience signs of menopause before age 40 suffer more heart attacks, both fatal and non-fatal.
This situation has been observed in both African American and white women, with differences in morbidity and mortality.
Comparison between white and African American women
The graphs analyzed highlight the disparities in cardiovascular health of both postmenopausal populations. Data show how African American women face a higher lifetime risk of coronary heart disease compared to white women.
An analysis of years lived free and with coronary heart disease reveals substantial differences. The statistics suggest a pressing call for preventive medical care in this group of women.
Characteristics of the population studied
An examination of the demographic characteristics of the women involved in the study shows that, of African Americans, significantly more experienced early menopause compared to their white counterparts. This finding could have important implications for public health and clinical approach.
The data reveal the average age of onset of menopause, as well as other risk factors associated with cardiovascular health in both cohorts.
This analysis highlights the urgent need for intervention strategies focused on the cardiovascular health of women undergoing early menopause, reiterating the importance of medical care and follow-up.
Understanding the relationship between early menopause and the risk of coronary heart disease is well-known for developing intervention programs.
Symptoms of early menopause
Early menopause (before age 40) usually presents symptoms very similar to those of long-established menopause, but they appear before the expected age.
Menstrual symptoms
- Absence or prolonged delays in menstruation (amenorrhea lasting several months).
- Irregular cycles, with changes in the amount of bleeding (more or less abundant).
Vasomotor symptoms
- Sudden hot flashes or “hot flashes”, usually in the face, neck and chest.
- Night sweats that interrupt sleep.
Sleep and mood problems
- Difficulty falling asleep or insomnia.
- Mood changes, irritability, anxiety or feeling sad.
Genitourinary symptoms
- Vaginal dryness and discomfort or pain during sexual intercourse (dyspareunia).
- Decreased sexual desire and, in some cases, urinary problems (itching, mild incontinence).
Other common symptoms
- Tiredness, headaches, weight gain (especially in the abdomen) and drier skin.
- In the long term, estrogen deficiency can increase the risk of osteoporosis and cardiovascular changes.
If you are under 40 years old and notice prolonged absence of your period along with hot flashes, night sweats or marked mood changes, it is advisable to consult a gynecologist to confirm whether it is early menopause and consider hormonal or supportive treatment.
Factors that contribute to early menopause
Early menopause is due, in general, to a decrease or early loss of ovarian function, and can have genetic, medical, immunological and lifestyle causes.
Genetic and hereditary factors
- Having a family history of early menopause (mother, sister) increases the risk several times.
- Some chromosomal disorders (for example, Turner syndrome or “fragile X”) are associated with early ovarian failure.
Diseases and medical treatments
- Autoimmune diseases such as thyroiditis, lupus, type 1 diabetes or rheumatoid arthritis can affect the ovaries and cause early menopause.
- Surgeries (oophorectomy or hysterectomy with removal of ovaries), chemotherapy or pelvic radiation therapy can damage the ovaries and lead to premature ovarian failure.
Lifestyle and environmental factors
- Smoking advances menopause on average by 1–2 years and is considered an important risk component.
- Exposure to certain toxic substances (solvents, pesticides, excessive alcohol or some occupational toxins) can contribute to premature aging of the ovaries.
Other less frequent factors
- Rare metabolic or enzymatic diseases (for example, galactosemia) can affect ovarian reserve.
- In many cases a clear cause is not identified and it is referred to as “idiopathic ovarian failure”, although genetic and autoimmune factors are usually involved in the background.
