Does underactive thyroid in pregnancy cause tiredness in pregnancy?
Short answer
Tiredness in Pregnancy is a common presentation of Underactive Thyroid in Pregnancy, although pregnancy itself can also cause fatigue.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- Key point
- Fatigue is common in pregnancy and needs testing to link it to thyroid function.
- Medicine advice
- Use prescribed thyroid treatment consistently and check supplement timing.
Understanding the overlap
An underactive thyroid produces too little thyroid hormone for the body's needs. During pregnancy, tiredness may occur with or without a thyroid problem, so the feeling cannot diagnose the cause. Other clues can include feeling unusually cold, constipation, dry skin, difficulty concentrating, or changes in weight. Blood tests measuring thyroid function help clarify whether treatment is needed.
What to do during pregnancy
Tell your maternity or primary-care clinician about persistent or worsening fatigue, especially if you have thyroid disease or take thyroid medicine. Do not start, stop, or change thyroid treatment without advice. Take prescribed medicine as directed and discuss its timing with supplements such as iron or calcium, which may affect absorption. Keep scheduled thyroid checks so treatment can be adjusted safely.
When to seek care
Contact your maternity team promptly if tiredness is severe, worsening, or accompanied by breathlessness, palpitations, fainting, chest pain, confusion, marked weakness, or reduced ability to function. Urgent symptoms require immediate medical assessment rather than waiting for a routine thyroid test.
Questions to ask
Could my fatigue be related to thyroid function, anaemia, sleep, or another pregnancy issue? Which blood tests do I need? When should thyroid levels be rechecked? How should I separate thyroid medicine from pregnancy supplements?

Questions people ask
Can tiredness alone show that my thyroid is underactive?
No. Tiredness has many causes in pregnancy, and thyroid blood tests are needed to assess thyroid function.
Should I stop thyroid medicine if I feel tired?
No. Speak with your clinician before changing treatment, because pregnancy can alter thyroid hormone needs.
