Can obesity cause hypertension?

Hypertension is persistently raised blood pressure. Extra body tissue can increase the work required to circulate blood and may influence kidney function and hormones that control salt and fluid balance. Sleep apnoea, kidney disease, some medicines, family history and pregnancy-related conditions can also raise blood pressure.

Hypertension often causes no warning symptoms, so a reading at a clinic, pharmacy or home monitor matters even when you feel well. Repeated measurements are used because one reading can be affected by pain, stress, caffeine or recent activity.

Arrange a blood-pressure check and keep a record of readings if your clinician recommends home monitoring. Take prescribed treatment consistently and do not change the dose without advice.

Regular activity, less salty processed food, a balanced eating pattern, good sleep and avoiding tobacco can support lower blood pressure. If weight management is appropriate, gradual changes are more practical to maintain than extreme plans. Mention snoring, daytime sleepiness or witnessed pauses in breathing because these may point to sleep apnoea.

Seek emergency help for very high blood pressure accompanied by chest pain, severe breathlessness, confusion, fainting, a severe headache, new weakness, facial drooping or difficulty speaking. Without these symptoms, arrange a prompt clinical review for repeatedly high readings or new swelling and breathlessness.

Ask how to measure blood pressure correctly, whether home readings are needed, what target is suitable for you, whether sleep apnoea or another condition should be checked, and how your medicines interact with exercise or weight changes.
