Why menopause makes you so tired
Fatigue during perimenopause and menopause is real and common. It's partly driven directly by fluctuating hormones, and partly by the knock-on effects of other symptoms — especially night sweats and disrupted sleep. If you're waking several times a night drenched in sweat, daytime exhaustion is inevitable.
Mood changes, anxiety and brain fog that often accompany this stage also sap energy. The result can be a deep tiredness that rest doesn't seem to fix.
Rule out other causes
It's worth remembering that not all mid-life fatigue is menopause. Iron deficiency (very common in women with heavy perimenopausal periods) and an underactive thyroid both cause exhaustion and are easily missed. Both are simple to check with a blood test.
Because these conditions are so treatable, a GP will often arrange iron studies and thyroid function tests when a woman presents with persistent fatigue — it's an easy win if one of them is the culprit.
What helps
Treating the root causes makes the biggest difference: improving sleep (a cool bedroom, consistent routine, treating night sweats), regular exercise, and managing stress. If night sweats are the main driver, treating them — often with MHT — can transform your energy.
A GP can help you work out what's contributing and put a plan together. If your fatigue is severe, persistent, or came on suddenly, get it checked rather than assuming it's 'just menopause'.
