What should you know about types of hypertension?

Primary hypertension develops gradually without one single identifiable cause. Family history, age, diet, activity, alcohol, stress, sleep, and body weight can all influence blood pressure. Secondary hypertension results from another condition or medicine, such as chronic kidney disease, obstructive sleep apnoea, or a hormone-related problem. It may begin suddenly or be harder to control.

A reading is only one part of the assessment. Blood pressure can vary with pain, illness, activity, caffeine, and anxiety, so clinicians may repeat measurements at home or during different visits. Untreated hypertension can increase strain on blood vessels and organs, including the heart, brain, and kidneys.

Use the measurement method your clinician recommends and keep a log of readings, timing, symptoms, and medicines. Take prescribed treatment as directed and do not stop it because one reading improves. Practical measures include reducing excess salt, staying active within your abilities, moderating alcohol, avoiding tobacco, and addressing poor sleep.

If readings remain high despite treatment, ask whether another condition or medicine could be contributing. Managing related conditions such as obesity or sleep apnoea may also support blood pressure control.

Arrange a routine review for repeatedly elevated readings or symptoms such as headaches that are new or persistent. Seek emergency help for very high readings accompanied by chest pain, severe breathlessness, fainting, new weakness, trouble speaking, confusion, or vision loss, because these can signal heart, brain, or blood-vessel complications.

Ask which type is suspected, how readings should be checked, whether kidney or sleep assessment is needed, and what treatment target and follow-up plan apply to you.
