Extreme tiredness in women is more than just needing an extra hour of sleep. It can impact daily life, affect relationships, reduce productivity, and be a sign of something more serious.
If you’re constantly exhausted even after a full night’s rest, you’re not alone. Research indicates that women are more significantly affected by fatigue than men.
A global meta-analysis covering over 600,000 participants found that 20.4% of adults worldwide report general fatigue.
Across various health conditions, women were found to be more fatigued than men, 50.3% compared to 43.8%. In the United States, 33% of women aged 51 and older report frequent tiredness, compared to 29% of men.
Common Causes of Extreme Tiredness in Women
There are many reasons why a woman might feel extremely tired all the time. Here are the most common causes:
1. Hormonal Changes
Women go through several life stages that involve hormonal shifts, menstruation, pregnancy, postpartum recovery, perimenopause, and menopause.
Each of these stages can bring fatigue. For example, PMS and heavy menstrual bleeding can cause iron loss and contribute to low energy.

2. Iron Deficiency (Anemia)
Iron-deficiency anemia is one of the top causes of extreme tiredness in women. According to global health data, about 30% of women aged 15–49 worldwide are anaemic.
This rate climbs as high as 80% during pregnancy in low-income countries. Without enough iron, the body can’t make healthy red blood cells to carry oxygen, leaving women drained and sluggish.

3. Thyroid Problems
An underactive thyroid (hypothyroidism) slows down the body’s processes, causing fatigue, weight gain, dry skin, and cold intolerance.
Women are far more likely than men to develop thyroid issues, particularly after pregnancy or during middle age.

4. Chronic Stress and Mental Health
Stress, anxiety, and depression can all deplete your energy. Emotional fatigue often presents as physical exhaustion.
Women are often expected to juggle multiple roles, professional, caregiver, and homemaker, which can add to daily stress. These pressures are a hidden but powerful contributor to persistent tiredness.

5. Sleep Disorders
Poor-quality sleep is a major contributor to extreme tiredness. Conditions like sleep apnea, restless legs syndrome, or insomnia can prevent deep, restorative sleep.
Research from Europe and Asia shows that up to 23.5% of adults in Asia and 12.7% in Europe report regular fatigue, often linked to sleep disturbances.
6. Poor Diet and Dehydration
Low-calorie diets, skipped meals, and low water intake can quickly sap your energy. A body lacking in nutrients such as B12, vitamin D, magnesium, or protein can’t function at full capacity.
Fatigue related to poor nutrition is widespread in women due to higher iron and nutrient demands, particularly during menstruation and pregnancy.

7. Underlying Medical Conditions
According to a research study, Fatigue can also be a symptom of more serious illnesses, such as diabetes, autoimmune disorders (like lupus or rheumatoid arthritis), infections, or even heart disease.
In some regions, 12.1% of women aged 18–50 have reported chronic fatigue lasting over six months, often associated with undiagnosed medical conditions.
Signs That Your Tiredness Is Not Normal
Fatigue becomes a red flag when it interferes with your day-to-day life. Look out for:
- Constant exhaustion, even after enough sleep
- Struggling to focus or remember things
- Feeling weak or dizzy
- Shortness of breath with mild activity
- Sudden mood changes or irritability
- Needing naps just to make it through the day
If you identify with several of these signs, it’s time to consider deeper causes.

When to Seek Medical Attention
Not all tiredness needs a doctor’s visit, but if you experience any of the following, make an appointment:
- Fatigue lasting more than two weeks
- Unexplained weight gain or loss
- Chest pain or palpitations
- Difficulty sleeping
- Loss of appetite
- Heavy or irregular periods
- New symptoms alongside fatigue (e.g., swollen glands, joint pain, headaches)
Extreme tiredness in women should never be ignored, especially considering data showing women report fatigue at up to three times the rate of men following illnesses like COVID-19. Post-viral fatigue and long COVID are also showing a strong gender bias, affecting more women globally.

What to Expect at the Doctor’s Office
Your doctor will ask about your sleep habits, stress levels, diet, and menstrual cycle. They may also:
- Perform a physical exam
- Order blood tests (e.g., thyroid function, iron levels, vitamin deficiencies)
- Ask about your mental health
- Check for signs of infection or inflammation
In some cases, they may refer you to a specialist such as an endocrinologist, sleep doctor, or mental health provider. Treatment will depend on the root cause, ranging from supplements and medication to dietary adjustments or therapy.

Managing and Preventing Extreme Tiredness
Improving energy often starts with small, manageable changes. Here are a few effective strategies:
- Get consistent sleep: Aim for 7–9 hours of uninterrupted rest. Go to bed and wake up at the same time every day.
- Eat nutrient-rich foods: Focus on whole grains, lean protein, fruits, vegetables, and iron-rich foods like spinach, lentils, and red meat (if you eat it).
- Stay hydrated: Aim for at least 6–8 cups of water daily.
- Reduce stress: Try breathing exercises, journaling, or light exercise such as walking or yoga.
- Limit caffeine and alcohol: Both can interfere with sleep and worsen fatigue.
- Move your body: Even light physical activity can increase energy levels and improve sleep quality.
According to a 2025 study in Geneva, 31% of adults reported severe fatigue two years into the COVID-19 pandemic, with women being the most affected. This shows the urgent need for women to take their symptoms seriously and seek support when needed.
