Low blood pressure, or hypotension, is often dismissed as nothing to worry about. For many women, it can be a normal part of how their body works. Yet in certain situations – linked to periods, pregnancy, the years around menopause, or medicines – it can signal something that needs attention and contribute to dizziness, tiredness, falls, or feeling generally unwell.
Many women notice symptoms like a “head rush” when standing up quickly, light-headedness that lasts, or feeling faint. These can tie into heavy periods that leave you drained, pregnancy changes, or shifts during perimenopause. If you have heavy bleeding that affects your daily life – flooding, clots, needing to change protection often, or missing work – it is worth discussing with your GP. NICE guidance on heavy menstrual bleeding stresses listening to how bleeding impacts your quality of life and checking for iron levels, including ferritin, because low iron can contribute to symptoms even before full anaemia shows.
During pregnancy, blood pressure often drops naturally in the first and second trimesters due to body changes. This is usually fine, but any dizziness, bleeding, or feeling that “something isn’t right” should be taken seriously. Postnatally, similar vigilance helps. Maternal reports from MBRRACE-UK repeatedly note that early signs of problems like bleeding or infection can sometimes be missed if symptoms are seen as just “normal for pregnancy.”
In the perimenopause and menopause transition, fluctuating hormones can affect how blood vessels work, sometimes leading to dizziness alongside other symptoms. NICE menopause guidance encourages open conversations about the full range of experiences and personalised support.
Medicines such as certain antidepressants or blood pressure treatments can sometimes lower pressure further or affect how you feel on standing. If you notice new dizziness after starting or changing medication, mention it at review appointments. Structured medication reviews in the NHS aim to look at the overall picture, especially for those on several medicines.
What you can do
Keep a simple note of symptoms, when they happen, and any link to your cycle, pregnancy, or medicines. Ask for your blood pressure to be checked lying and standing if you feel dizzy. Request blood tests for iron and ferritin if heavy periods are an issue. Bring a list of questions to appointments – your experiences matter.
Early attention to these patterns can prevent bigger problems and help you feel more in control of your health across life stages.
