What Happens to Your Muscles During Menopause - and How Can You Deal With It?

In short: Menopause is the absence of periods for 12 months in a row, at an average age of 51. At this stage oestrogen, progesterone and testosterone fall, muscle repair slows, and a woman may lose 0.5–1.5% of her working muscle mass. To keep your strength: resistance exercise 2–3 times a week, enough protein, and vitamin D and creatine under medical supervision.

Menopause is not limited to hot flashes and changes in the menstrual cycle; it also affects your muscles. As hormone levels decline, you naturally lose muscle strength, size, and function gradually. But the good news is that you can do a lot to protect your muscles and maintain your strength and independence as you age. This guide explains the causes of muscle loss during menopause and the steps you can take to stay healthy and active.

What is menopause?

Menopause is the stage in which a woman’s menstrual cycle stops for 12 consecutive months, representing the end of the natural reproductive years. The average age of natural menopause is about 51 years in many societies, with natural individual variation.

Why do muscles weaken during menopause?

Hormones do not only regulate the menstrual cycle; they also help maintain the health of your muscles. During menopause, your body produces lower amounts of estrogen, progesterone, and testosterone. These changes affect your muscles in several ways:

• Slower muscle repair: Lower hormone levels reduce your body’s ability to build and repair muscle tissue.
• Reduced cellular energy: Your muscles do not produce energy efficiently, which may make you feel tired and weak.
• Increased inflammation: Estrogen normally helps control inflammation. When it decreases, inflammation in the body may increase, leading to muscle breakdown and weight gain.

How does muscle mass change during menopause?

Some research indicates that women may lose between 0.5% to 1.5% of their muscle mass during the menopause period, equivalent to about 119 grams annually according to some estimates. At the same time, body fat percentage tends to increase.

But more importantly, the impact of these changes is not reflected the same way in all women:

• Women who do not exercise (inactive) lose muscle faster.
• Physically active women, especially those who practice strength training, can slow down or even reduce the rate of muscle loss.

What are the real-world effects of muscle loss?

Muscle loss is not limited to appearance only; it affects your daily life and general health.

Hot flashes

Some studies indicate that exercise, especially strength training, may help reduce the frequency and severity of hot flashes in some women, noting that results vary from woman to woman and need further research.

Mood and depression

Both strength training and aerobic exercises (such as walking, cycling, or swimming) can contribute to improving mood and alleviating some symptoms of depression. Some research also links lower muscle mass with higher rates of depression in postmenopausal women, but more studies are needed to confirm this relationship.

Weakness and falls

Muscle loss leads to weakness and instability on the feet, which may increase the risk of falls, fractures, and reduced quality of life. Some studies also indicate a link between decreased muscle mass and an increased risk of certain long-term health problems, which calls for more attention rather than excessive worry.

How can you protect your muscles?

The good news is that there are many natural and effective ways to maintain your muscle strength during and after menopause.

1. Strength (resistance) training

This is one of the most effective non-pharmacological methods for combating muscle mass loss. Strength training involves using weights or resistance, such as using dumbbells, resistance bands, or body weight (such as squats or push-ups).

Simple guidelines:

• Aim to exercise two to three times a week, on non-consecutive days.
• Focus on compound exercises that work multiple muscle groups at once (such as lunges, chest presses, and rowing).
• If you are a beginner or have a weaker build, start with lighter weights - about 40-50% of your maximum effort, and gradually increase them as your strength grows to about 60-80%.
• Perform one to three sets, each set consisting of 8 to 12 repetitions per exercise.

2. Hormone Replacement Therapy (HRT)

Hormone replacement therapy can help alleviate many menopausal symptoms, but its direct effect on muscles is still not entirely clear. Some studies indicate that combining hormone therapy with strength training may enhance muscle growth more than exercise alone, while other studies do not show a clear additional benefit. It is important to consult your doctor to find out whether this therapy is suitable for your condition.

3. Eat an adequate amount of protein

Protein is the essential building block for muscle. The generally recommended daily amount (0.8 grams per kilogram of body weight) may not be sufficient for all women over fifty. Some experts suggest the following as a general guideline that can be discussed with a nutrition specialist or doctor:

• 1.0 to 1.2 grams per kilogram of body weight daily for healthy older women.
• 1.2 to 1.5 grams per kilogram if there is a chronic condition or very limited physical activity — except for women with kidney disease, who should follow their doctor’s advice on protein intake.

Combining protein-rich meals with strength training makes your muscles more responsive to building new tissue.

4. Dietary supplements

Vitamin D: Taking an appropriate daily dose (as recommended by a doctor, sometimes reaching up to 1000 IU or more in confirmed deficiency cases) may contribute to improving grip strength and overall muscle function, which is especially useful if sun exposure is limited. The appropriate dose should always be determined in consultation with a doctor after testing vitamin levels.

Creatine: Some studies indicate that taking 3 to 5 grams of creatine monohydrate daily may be beneficial, but it is preferable to consult a doctor before starting, keeping in mind that supplements give their best results when combined with exercise, not as a substitute for it.

Conclusion: Make your muscle health a priority

Instead of relying on hormone therapy alone, it is helpful to focus on lifestyle: maintaining activity, following a healthy diet, and gradually building strength. Structured strength training is generally recommended, in addition to aerobic exercises, within a plan suited to your health condition.

Regular exercise, consuming an adequate amount of protein, and appropriate supplements such as vitamin D and creatine - under medical supervision - are among the best available ways to prevent and maintain muscle strength.

Caring for your muscles can also help alleviate some other menopausal symptoms, such as mood swings and hot flashes, though more research is needed to confirm the extent of this effect. It is likely that in the future, exercise and proper nutrition will receive greater attention within healthcare for menopausal women, with the aim of improving quality of life and maintaining functional independence.
