pregnancy with fatigue

Overview

Fatigue is extreme tiredness that does not get better with rest. During pregnancy, it is very common, especially in the first and third trimesters. Your body is working hard to grow a baby, and that takes extra energy.

Yes. Fatigue affects most pregnant women at some point. It is especially common in the first 12 weeks and again in the final weeks before the baby is born.

Anyone who is pregnant can feel fatigue. It often affects women in the first trimester (weeks 1 to 13) and the third trimester (weeks 28 to 40). You may feel it more if you are carrying twins, already have children, or are low on iron.

Symptoms

Common symptoms

• Feeling exhausted even after a full night of sleep
• Needing more naps than usual
• Lacking the energy to do everyday tasks
• Feeling heavy, weak, or achy in the legs
• Having trouble concentrating or remembering things (often called 'pregnancy brain')

Symptoms in children

• Not applicable. Fatigue during pregnancy is a condition that affects the pregnant person, not children.

Symptoms in older adults

• Not applicable. This article is about fatigue during pregnancy. Older adults may experience fatigue for different reasons.

Causes

Main causes

• Changes in hormones, especially higher levels of progesterone, which can feel like a sedative
• Your body making more blood to support the baby, which makes your heart work harder
• Lower blood pressure and blood sugar, especially in early pregnancy
• Sleep problems caused by physical discomfort, needing to urinate at night, or worry
• Iron deficiency anemia, which means your blood has fewer red blood cells to carry oxygen

Risk factors

• Carrying twins or more
• Having fatigue before pregnancy or in a previous pregnancy
• Existing health conditions such as anemia, thyroid problems, or depression
• Poor sleep habits or sleep apnea
• High levels of stress, work demands, or caring for other children
• Not eating enough or not drinking enough fluids

When to see a doctor

See a doctor urgently if:

• Call your maternity unit or doctor immediately if you have any of the emergency symptoms listed above.
• If you have moderate bleeding, a fever, or cannot keep fluids down, seek care the same day.

Book a routine appointment if:

• If fatigue is long-lasting and makes it hard to manage daily life, book an appointment.
• If you also feel very short of breath, look pale, or have a racing heart, you may need a blood test for anemia.
• If you feel low, anxious, or hopeless, talk to your midwife or doctor. This is important and can be treated.

Diagnosis

Your healthcare provider will ask about your symptoms, sleep, diet, and daily routine. They will likely check your blood pressure and may feel your lower belly to see how the baby is growing. They may also listen to your heart and lungs.

Tests that may be done

• Blood tests to check for anemia or thyroid problems
• A urine test to check for infection or protein in the urine
• A blood pressure measurement
• An ultrasound, if needed, to check the baby's growth

What to expect at your appointment

The appointment is usually quick and can be reassuring. Be honest about how tired you feel. Your provider has seen this in many patients and will not judge you. They can offer practical, safe advice based on your situation.

Treatment

There is no single cure for pregnancy fatigue, but there are many safe ways to feel better. The main treatment is rest and conserving your energy. If a cause such as anemia is found, your provider can offer a treatment that is safe during pregnancy.

Self-care at home

• Listen to your body and rest when you need to. A 20-minute nap can help.
• Keep a regular sleep schedule. Go to bed and wake up around the same time each day.
• Ask family members or friends for help with household tasks and errands.
• Drink plenty of water and eat small, regular meals to keep your energy steady.
• Try gentle physical activity, like short walks or pregnancy yoga, to boost your energy.
• Limit caffeine, especially in the afternoon and evening.
• Sit with your legs up for a few minutes during the day to improve blood flow.

Medical treatments

If blood tests show a problem, your provider may suggest a safe supplement, such as iron or folic acid, or another treatment depending on the cause. Never take any supplement during pregnancy without talking to your provider first. If a thyroid condition or an infection is found, your provider will treat it in a way that is safe for you and your baby.

Living with this condition

Plan your day around your energy levels. Do tasks that need focus when you feel most awake, and save easier tasks for when you are tired. Sit down when you can – for example, while folding laundry or preparing vegetables. Do not feel guilty about delegating or saying no to extra obligations.

Lifestyle tips

• Set a consistent bedtime and wake time, even on weekends.
• Take short breaks during the day, even if they are just five minutes.
• Keep moving gently, but do not push yourself to exhaustion.
• Avoid heavy lifting and standing for long stretches.
• Wear comfortable shoes and loose clothing.

Diet and exercise

Eat small, frequent meals that include protein, whole grains, fruits, vegetables, and healthy fats. Drink water throughout the day. Aim for about 20 to 30 minutes of moderate walking most days, unless your provider advises otherwise. Movement can actually reduce fatigue, but never exercise to the point of feeling faint.

Mental health and emotional wellbeing

Constant tiredness can feel frustrating and worrying. You may miss your usual energy or feel guilty that you are not doing enough. Remind yourself that fatigue is temporary and a sign your body is working hard. If you feel down, anxious, or hopeless for more than two weeks, talk to your provider. They can support you.

Prevention

You cannot fully prevent pregnancy fatigue, because it is a natural response to growing a baby. But you can reduce how much it affects you by eating well, staying hydrated, getting enough rest, and keeping stress manageable.

Screening programmes

Routine pregnancy appointments include blood pressure checks and screenings for anemia. These checks can catch health issues early, before they make fatigue worse.

Complications

If left untreated

• Untreated anemia can make your heart work harder and can raise the risk of preterm birth or low birth weight.
• Undetected pre-eclampsia (a serious condition with high blood pressure) can become dangerous.
• Severe exhaustion may lead to poor nutrition or dehydration if you are too tired to eat or drink enough.

Long-term outlook

For most women, fatigue comes and goes during pregnancy and gets much better after the baby is born. With rest, good nutrition, and support, you can manage it safely. If a cause like anemia or a thyroid issue is found, treatment often brings your energy back. Your body is doing something amazing – be kind to yourself and ask for help when you need it.
