What does menopause fatigue feel like?
During the transition to menopause, many people say “I’m not myself anymore.” You don’t wake up rested. A slump hits in the afternoon. Things you used to do easily now feel heavy. Sometimes the tiredness is more in your mind than in your body: focusing, making decisions and following a conversation get harder.
The NHS lists tiredness among the symptoms of menopause and perimenopause. It notes that feeling very tired can also affect your mood and memory (NHS, Symptoms). The NHS page on tiredness also lists menopause as one possible cause of fatigue (NHS, Tiredness and fatigue).
Fatigue is one of the most commonly reported complaints of menopause. In a meta-analysis combining 321 studies and about 482,000 women, roughly 64 percent of midlife women reported physical and mental exhaustion. That was the second-highest rate among the 19 symptoms studied, after joint and muscle complaints (Fang et al., 2024). The authors note that the studies differed a lot from one another, so the figure is a rough idea, not an exact number.
Why does menopause make you tired?
There is no single cause of fatigue. Usually several factors stack up.
Disrupted sleep
The NHS lists difficulty falling asleep or staying asleep among menopause symptoms. It also notes that poor sleep can lead to irritability, stress and anxiety (NHS, Symptoms). Waking up with night sweats, changing your clothes and not being able to get back to sleep can happen several times in one night. It is no surprise that you feel tired the next day. We cover both topics in separate articles: Menopause insomnia and Night sweats.
Night sweats sometimes affect your relationship too. Throwing the covers off and on, opening the window or having to sleep in separate beds can create tension with your partner. Talking about it is one way to protect both of your sleep.
Symptoms feed each other
The SWAN study in the US followed 3,289 women and 58 different symptoms over 16 years. Fatigue appeared in the same symptom clusters as hot flashes, pain and sleep problems. In one group of women, fatigue and emotional complaints dominated (Harlow et al., 2017).
The same study shows something else that matters: these symptom clusters were already clear in early midlife, before menopause. Most women stayed in the same cluster across the menopause stages (Harlow et al., 2017). So part of the fatigue was there before menopause too and should not be blamed on hormones alone. Being in a high-symptom cluster was strongly linked with financial hardship, higher body weight and smoking (Harlow et al., 2017).
Mood and mental tiredness
The NHS also lists mood swings, low mood and depression among menopause symptoms. Problems with memory and concentration, often called “brain fog,” are on the same list (NHS, Symptoms). These symptoms intertwine with fatigue. After a bad night, both your body and your mind are tired, and when you are tired your mood drops more easily. It is hard to tell which comes first. That is why it matters to tell your doctor about changes in your mood along with the tiredness.
Heavy periods and iron deficiency
In perimenopause, periods are sometimes heavier than before (NHS, Symptoms). The NHS lists heavy periods as one of the most common causes of iron deficiency anemia (a lack of red blood cells caused by low iron). Besides tiredness and low energy, anemia can cause shortness of breath, heart palpitations, pale skin and headaches (NHS, Iron deficiency anaemia). We cover heavy bleeding in a separate article: Heavy periods before menopause.
How does fatigue affect work and home life?
Menopause fatigue usually lands in the busiest stretch of life. Responsibility at work has grown. At home, children, aging parents and housework all sit on your shoulders at once. When fatigue is added on top of that load, you may feel you are not good enough.
This is not a question of willpower. Not being able to concentrate in a meeting, or having no energy left for anything when you get home in the evening, is a real symptom. In the SWAN study, women with heavier symptoms more often rated their health as “fair” or “poor” (Harlow et al., 2017). Telling the people around you and your doctor about your tiredness is the first step toward sharing the load.
What else can cause fatigue besides menopause?
Being in the menopause years does not mean menopause is the only cause of your tiredness. The NHS lists these causes (NHS, Tiredness and fatigue):
- Lack of sleep and irregular sleep
- An unbalanced diet and too little movement
- Iron deficiency anemia
- Thyroid problems; on this page the NHS gives an overactive thyroid as an example
- Depression, stress and big life changes
- Sleep apnea: breathing stops again and again during sleep; it shows up as loud snoring and waking up choking
- Diabetes: extreme thirst, frequent urination and weight loss may come with it
| What you notice | Could be linked to menopause | Suggests another cause / see a doctor |
|---|---|---|
| Sleep broken by night sweats, tired the next day | Yes, common | GP if it disrupts daily life |
| Very heavy periods along with tiredness | Partly | Iron deficiency; blood test |
| Snoring, breathing stopping during sleep | No | Sleep apnea; GP |
| Extreme thirst, frequent urination, weight loss | No | Diabetes; doctor |
| Lack of motivation, hopelessness, no pleasure in things | Partly | Depression; doctor or mental health professional |
What can you observe yourself?
This information helps when you see your doctor:
- How long have you been tired? Every day, or some days?
- How many times do you wake up at night? Do you have night sweats?
- Are your periods heavier than before? Do you have clots or flooding?
- Has anyone told you that you snore or stop breathing in your sleep?
- Is your mood low, or do you have a lack of motivation or no pleasure in things?
- Has your weight, appetite or thirst changed?
The NHS lists some general steps for tiredness: going to bed and getting up at the same time every day, aiming for 6 to 9 hours of sleep, keeping the bedroom dark, quiet and not too warm, avoiding food, caffeine and exercise in the two hours before sleep and screens in the last hour, and quitting smoking and cutting down on alcohol (NHS, Tiredness and fatigue).
When should you see a doctor about fatigue, and what should you ask?
The NHS advises contacting your GP if you have been tired for a few weeks with no known cause, if tiredness affects your daily life, or if it comes with weight loss or changes in mood (NHS, Tiredness and fatigue). If needed, your doctor will order a full blood count; this test needs no preparation (NHS, Iron deficiency anaemia).
At the appointment you can ask:
- Does my tiredness fit with the menopause transition?
- Do I need tests for anemia and thyroid problems?
- Should I be assessed for sleep apnea?
- Who can I talk to about the changes in my mood?
