Why Women Gain Weight During Perimenopause and Menopause

Perimenopause is the transitional phase leading up to menopause, typically starting in your mid-30s and lasting anywhere from 4 to 10 years, some women even 15 years (everyone is very different). During this time, your body undergoes hormonal changes that affect various aspects of your health, including weight. One of the most common symptoms is weight gain, particularly around the abdomen, which happens even if you haven’t changed your diet or exercise routine. This is due to hormonal fluctuations that slow down your metabolism, making it harder to lose weight.

Along with weight gain, other symptoms of perimenopause include heavy periods and clotting, rage, mood swings, hot flashes (closer to menopause but not for everyone), night sweats, sleep disturbances, low energy and fatigue, decreased libido, joint and muscle pain, and brain fog. Menopause, which officially starts after 12 consecutive months without a period, marks the end of the reproductive years. Understanding these symptoms and how they affect your body is important so you can manage it effectively.

Postmenopause begins after 12 consecutive months without a period and continues for life. Many menopause symptoms, like hot flashes, subside, but the lower oestrogen levels may increase the risk of osteoporosis and heart disease. Symptoms like vaginal dryness and decreased libido can persist, so ongoing health management, including exercise and regular check-ups, is important for long-term well-being.
