High blood pressure when you are young and not overweight

Body weight is only one influence. Family tendency, high salt intake, alcohol, nicotine, stress, some medicines and hormonal or kidney conditions can affect pressure. A single high reading may reflect pain, anxiety, recent exercise or an incorrectly sized cuff. Repeated measurements at home or ambulatory monitoring can show whether pressure stays high outside the clinic.

A clinician may review medicines and supplements, examine your heart and circulation, and request blood and urine tests. Depending on your history, they may assess the kidneys or sleep-related breathing problems. Untreated hypertension can strain blood vessels and organs over time, even when you feel well.

Arrange a routine appointment and bring a record of readings, including when they were taken and whether you had rested beforehand. Sit quietly, keep both feet supported and place the cuff on bare skin at heart level. Do not stop prescribed medicine because a reading improves or because you feel normal.

Keep meals lower in salty processed foods, stay physically active in a way you can maintain, avoid tobacco and moderate alcohol. Tell the clinician about snoring, daytime sleepiness, headaches, palpitations and any close relatives with early hypertension. Further information is available on [Hypertension](/conditions/hypertension/) and [Chronic Kidney Disease](/conditions/chronic-kidney-disease/).

Seek emergency care for a very high reading accompanied by chest pain, severe breathlessness, new weakness or numbness, trouble speaking, confusion, fainting or sudden vision change. These symptoms can signal a serious problem such as [Stroke](/conditions/stroke/) or [Angina](/conditions/angina/). Without warning symptoms, contact a clinician promptly about persistently high readings rather than trying to diagnose the cause yourself.

Ask which readings should be repeated, whether home monitoring is suitable, what tests might identify a kidney or hormone-related cause, and what lifestyle change would make the clearest difference for you. Ask how soon your result should be reviewed.
