Extreme tiredness in the first trimester: what to know

Hormonal changes, nausea, vomiting, emotional adjustment and the body's work of supporting pregnancy can reduce energy. Poor sleep or difficulty eating and drinking can make it worse. Fatigue may also relate to anemia, thyroid disease, infection, low mood or another condition. Tiredness alone cannot confirm whether a pregnancy is progressing normally, so describe its intensity and effect on daily life rather than trying to interpret it as a test result.

Plan demanding tasks for the time of day when you feel most alert. Rest when you can, accept practical help, drink often and choose small meals or snacks if nausea limits eating. Rise slowly if you feel light-headed. Keep taking only supplements recommended for your pregnancy, and ask before using medicines for nausea or fatigue. Arrange routine antenatal care and mention exhaustion that prevents normal self-care.

Seek urgent help for heavy bleeding, severe one-sided abdominal pain, fainting, chest pain, difficulty breathing or confusion. Contact your maternity clinician promptly for repeated vomiting, inability to keep fluids down, very dark or infrequent urine, fever, racing heartbeat, marked dizziness or fatigue that is rapidly worsening. These signs can cause dehydration or point to a problem needing treatment.

Ask whether your blood count and thyroid need checking, how to manage nausea safely, which activities are reasonable, and which symptoms should prompt an urgent call.
