Fatigue in the second trimester of pregnancy

Some people feel more energetic after early-pregnancy nausea settles, while others remain tired as the body supports a growing pregnancy. Poor sleep, emotional strain, reduced appetite, dehydration, or low iron can add to the heavy, washed-out feeling. Anaemia may cause tiredness with pale skin, breathlessness on ordinary activity, headaches, or a fast heartbeat. These symptoms do not identify one cause by themselves.

A clinician may ask about sleep, food, fluids, mood, bleeding, breathlessness, and other symptoms. Blood tests can help check for anaemia and other explanations when fatigue is persistent or interferes with daily life.

Keep a regular sleep routine and allow short rest periods before exhaustion builds. Eat regular meals and include iron-containing foods such as beans, lentils, leafy vegetables, eggs, meat, or fortified foods when suitable for you. Drink regularly, especially in hot weather, and use gentle movement such as an easy walk if your maternity team has not advised restrictions.

Take only pregnancy supplements or medicines recommended by your maternity clinician. Do not start an iron supplement or stop a prescribed treatment without checking first, because the right choice depends on your symptoms and test results.

Contact your maternity team or a doctor promptly if fatigue is suddenly severe, keeps worsening, or prevents normal activities. Seek urgent help for chest pain, fainting, severe breathlessness at rest, heavy bleeding, severe abdominal pain, confusion, or inability to keep fluids down. Fever, a new cough, painful urination, or marked thirst with very little urine also warrants medical advice.

Could my symptoms suggest anaemia, and do I need a blood test? Which foods, supplements, and activity level are appropriate for me? What changes should prompt same-day maternity advice?
