Half of Women Do Not Seek Care for Menopausal Symptoms.
Findings from a Survey on Basal Body Temperature and Menopausal Awareness.
OMRON Healthcare, Co., Ltd. (Head Office: Muko, Kyoto, President & CEO: Ayumu Okada) conducted an awareness survey on basal body temperature and menopausal symptoms among 900 women in their 30s to 50s in commemoration of International Women's Day on March 8, 2025. International Women's Day was established by the United Nations in 1975 to celebrate gender equality and to honor the remarkable achievements and courageous actions of women.
In this survey, 27.7% of respondents reported experiencing symptoms they associate with menopause. The most reported symptom was “fatigue or lack of energy,” followed by “hot flashes” (sudden feelings of heat in the face or body) at 57.0%, and “insomnia or poor sleep quality” at 47.0%. When asked about measures taken to address these symptoms, about half said they “do not take any specific measures.” Furthermore, 23.3% of respondents believed there is a connection between basal body temperature and menopausal symptoms.
The Company’s vision for the cardiovascular business is to achieve ZERO incidence of cerebrovascular and cardiovascular diseases (Going for ZERO). In addition, products and services are offered to support women’s health at every stage of life, along with various awareness-raising initiatives. Based on the results of this survey, the risks of menopausal hypertension and the importance of home blood pressure monitoring will be widely communicated, with the goal of reducing cardiovascular events for as many women as possible.

Survey Results Details
1. When asked about menopause, 52.0% of respondents said they feel anxious.
Anxiety was highest among those in their 40s (62.3%), followed by those in their 30s (52.7%) and 50s (41.0%), indicating that people approaching or entering menopause tend to feel the most anxiety.


2. 5.0% of people in their 30s and 28.0% of people in their 40s feel symptoms that they think are menopausal symptoms. 50.0% of people in their 50s feel symptoms.
When asked whether they experience symptoms they believe are related to menopause, 5.0% of women in their 30s and 28.0% in their 40s answered “yes.” In their 50s, 50.0% reported experiencing symptoms. Those who answered “I don't know” accounted for 23.8% of the total. Additionally, approximately half of the respondents answered “No.”


3. Top Menopausal Symptoms by Age Group
When asked about specific menopausal symptoms, the most common was “fatigue or lack of energy,” reported by 58.6% of respondents overall. This was followed by “hot flashes” (sudden feelings of heat in the face or body) at 57.0% and “insomnia or poor sleep quality” at 47.0%. By age group, 70.2% of women in their 40s reported fatigue or lack of energy, while 69.3% of those in their 50s reported hot flashes, indicating that the most common symptoms differ by age.


4. Nearly half of women do not take any specific measures for menopausal symptoms
When asked about measures taken to address menopausal symptoms, the largest group at 49.8% of respondents answered that they do not take any specific measures. Some women reported using supplements or health foods (25.7%) and engaging in exercise or dietary management (22.9%) as coping strategies. However, regardless of age group, about half of the respondents did not take any measures. Additionally, only 4.4% of women reported measuring their basal body temperature as part of their care.


5. Basal Body Temperature Measurement
60 percent of respondents have measured their basal body temperature. When asked about their reasons, 41.5% said it was “as part of trying to conceive,” followed by 29.4% who measured it “to understand their menstrual cycle.” Only 2.4% reported measuring it “to understand menopausal symptoms.”




6. Relationship Between Basal Body Temperature and Menopausal Symptoms
When asked whether they feel there is a connection between basal body temperature and menopausal symptoms, 23.3% of respondents answered “Yes,” while 67.8% answered “Don’t know.” This reveals that most people do not perceive a clear relationship between basal body temperature and menopausal symptoms.


Comment from Dr. Ruriko Tsushima, M.D., Ph.D.
The survey results show that awareness of care and treatment for menopausal symptoms remains low and limited. As menopause approaches, ovarian function gradually declines, leading to changes in the menstrual cycle and basal body temperature. Additionally, as menopause nears, progesterone, which previously maintained the high-temperature phase, decreases, causing basal body temperature to no longer show a high-temperature phase but instead remain in the low-temperature phase. In this way, basal body temperature and menopausal symptoms are closely related. Therefore, it is extremely important to record basal body temperature daily to better understand one’s own body.
Furthermore, for about 10 years around menopause, the decrease in estrogen, one of the female hormones, is believed to disrupt the autonomic nervous system and affect blood pressure control. Combining blood pressure measurements can help balance the autonomic nervous system and contribute to overall health management.
During the menopausal period, it is important to consult your gynecologist or internist and undergo both treatment and care. It is also essential to maintain a balanced diet, get adequate sleep, and engage in moderate exercise.
