What should you know about first line therapy for hypertension?

Hypertension means blood pressure remains high across appropriate measurements. Treatment is individual: clinicians consider repeated readings, age, pregnancy, kidney health, diabetes, cardiovascular risk, and existing conditions. Lifestyle support may include reducing excess salt, being physically active, avoiding tobacco, moderating alcohol, improving sleep, and addressing obesity when relevant. Medicine may be started alongside these measures rather than waiting for lifestyle changes to work alone. The goal is sustained protection of the heart, brain, kidneys, and blood vessels.

Use a validated monitor if home readings are part of your plan, and record the date, time, and reading. Take medicine consistently and ask before stopping, doubling, or sharing doses. Report dizziness, swelling, cough, faintness, or changes in urination because the regimen may need review. Mention medicines such as anti-inflammatory painkillers and any supplements. Conditions including chronic kidney disease, heart failure, obstructive sleep apnoea, and obesity can change the assessment, so bring relevant records to appointments.

Get emergency help for chest pressure, severe breathlessness, collapse, sudden weakness or numbness, facial drooping, new trouble speaking, or sudden loss of vision. These may indicate [Stroke](/conditions/stroke/) or another urgent problem. Seek prompt clinical advice for repeated very high readings, severe headache with visual symptoms, or new medicine effects. Do not use the absence of symptoms as proof that hypertension is controlled.

Ask what readings and health factors guide treatment, how often follow-up is needed, which lifestyle change is most useful for you, and when blood tests are required. Ask how another condition could affect your plan.
