During menopause, your ovaries gradually stop producing oestrogen and progesterone. In the early stages of menopause, both sex hormones fluctuate and decrease significantly. When oestrogen levels begin to drop, it affects collagen production—a protein that ensures strong and flexible muscles.
Oestrogen supports collagen production. When oestrogen production decreases, collagen levels also decline. This can impact your muscles, causing them to feel painful or tense.
The decrease in oestrogen also affects muscle mass. Muscle mass diminishes, and muscles become less elastic. You may not feel as flexible as before. Your joints can also be affected, leading to stiff hands, sore knees, or painful shoulders.
Additionally, the hormone leptin plays a role. Leptin suppresses appetite but also influences muscle mass. Hormonal fluctuations during menopause can make you less sensitive to leptin (a condition known as leptin resistance). This can cause inflammation in the body and increase muscle pain.
From the age of 30, muscle mass decreases by three to eight per cent every decade. This decline accelerates after the age of 60. Losing muscle mass is a natural part of ageing. Many women begin to notice this as they enter menopause. Some experience it early in the first years of menopause, known as perimenopause. In postmenopause, the likelihood of muscle symptoms increases.
