High Blood Pressure: Prevention, Symptoms, and Treatment

The average blood pressure of a person is 120/80 mmHg and they are feeling just fine, somewhere in Jaipur right now. They don't experience pain. They are not dizzy. They have no idea. They will be reading that elevated pressure for months or years, damaging their arteries, stressing their heart, compromising their kidney function and increasing the likelihood of a stroke or heart attack that will come in due course - and unannounced.

That's why hypertension is known as "the silent killer. The World Health Organization estimates that it's the biggest risk factor for death in the world, with the majority of those with it unaware. This problem is especially severe in India; the prevalence of hypertension is estimated to affect more than 213 million Indians by 2025, with awareness and treatment being alarmingly low. This guide provides an explanation of what High Blood Pressure is, what causes it, the most common hypertension symptoms (which is silent), and what hypertension treatment entails.

What High Blood Pressure Actually Is

Blood Pressure is the pressure of blood against the artery walls as blood circulates through the body. It is noted as two numbers: systolic (when the heart pumps) over diastolic (when the heart is resting between beats). The old normal was a reading of 120/80mmHg. The 2025 AHA/ACC Hypertension Guideline reaffirms that the threshold for diagnosis of hypertension is 130/80 mmHg and that starting treatment intervention early will lower the lifetime risk of heart attack, stroke, kidney disease and cognitive decline.

Blood pressure classification and implications for management are summarized in the table below:

There is a threshold for an hypertensive crisis: If the reading exceeds 180/120 mmHg, it's a medical emergency. Call for emergency help at once if the pain occurs in the chest, severe headache or vision changes or breathlessness. Never wait and see if it falls.

Symptoms of High Blood Pressure

The most important thing to remember about high blood pressure symptoms is that most people don't have any of them. In the vast majority of patients, no one feels ill, sick, or painful due to high blood pressure. This is not a hyperbole. It is the key clinical characteristic of the disease.

Headache, dizziness, flushing of the skin, nose bleeds are all common symptoms that people associate with high blood pressure, but they only happen in the most extreme or rapid increases of blood pressure.  

Most people with severe hypertension have no symptoms. If you have these symptoms, it is likely your blood pressure is not dangerously high. The only way to determine blood pressure is to take blood pressure measurements.

Symptoms will occur only if a person has had high blood pressure for a long time and it has caused damage to the organs:

• Persistent headache If the headache is persistent, especially at the back of the head and is worse in the morning it can indicate chronically raised pressure.
• Visual disturbances or blurring: Blurring of the vision or changes in vision may be a sign of hypertensive retinopathy which is the damage to the blood vessels in the retina.
• Breathlessness on exertion: If a person develops shortness of breath on exertion that wasn't there before, it could mean that the heart has been having to work against high resistance to blood flow for so long that it has resulted in hypertensive heart disease.
• Swelling of the ankles: Increased ankle swelling in a hypertensive patient may be a sign of early heart or kidney strain.
• Nocturia: One early sign of kidney involvement in hypertension is waking at night to pass urine very often.

The following are not warning signs, so much as signs of beginning organ damage. The real early treatment of hypertension takes place prior to all of them, with standard blood pressure checks. In India, adults over the age of 25 should have their blood pressure monitored at each health examination and at least once a year, even if the blood pressure was previously normal.

Causes of High Blood Pressure: Primary vs Secondary.

In about 90-95% of cases, the cause of hypertension remains unknown. It takes years to form and is caused by a combination of genetic makeup and lifestyle. This is referred to as primary or essential hypertension. The other 5-10% suffer from secondary hypertension (high blood pressure due to a specific underlying cause). It is important to know what the secondary causes are because by treating the underlying condition, you can cure the high blood pressure

Risk factors for Primary Hypertension:

• Age:  As people get older, arteries get stiffer, causing the systolic blood pressure to gradually increase. Prevalence of hypertension increases steeply after 50 years of age, but is becoming more prevalent in younger adults in India.
• Heavy salt in the diet :  Indian people have a high intake of salt (from pickles, papad, processed food, salting in cooking etc.). Sodium increases blood pressure by increasing fluid retention and resistance of the arteries. Under 5gms or less than 1 teaspoon of salt is recommended per day by the WHO which is even less than what most Indians consume.
• Overweight and obesity:  Excess body weight (abdominal obesity, a risk factor prevalent in South Asians at normal BMI) is one of the most significant modifiable risk factors. Each 5 kg of drop in weight brings a significant drop in blood pressure.
• Physical inactivity:  Leads to decreases in heart efficiency and increases peripheral vascular resistance. Exercise (30 mins most days) results in a decrease in systolic BP of 5-8 mmHg.
• Tobacco use:  Nicotine is an acute vasoconstriction agent, with every use. Chronic smoking also injures the walls of arteries, promoting atherosclerosis and increasing resting vascular resistance.
• Diabetes and insulin resistance:  Insulin resistance   which occurs quite commonly in Indian population even prior to the presence of diabetes  is associated with increased sodium retention and sympathetic nervous system activation, both of which lead to increased blood pressure. There is a very strong association between hypertension and diabetes.
• Family history (father before age 55 or mother before age 65): First-degree relatives who have hypertension significantly increase an individual's life-time risk.

Chronic stress:  This is when psychological stress is ongoing, causing an increase in the heart rate and vascular tone. Stress creates indirect behaviours, such as unhealthy eating, alcohol consumption and poor sleep which exacerbate the direct impact.

Risk Factors for Secondary Hypertension

A general physician in Jaipur would consider secondary causes when the hypertension occurs in a person below 30 years age and they don't have any apparent risk factors, in case the blood pressure is extremely difficult to control even after taking multiple medicines, and in case certain clinical features make them suspect of any specific cause:

• Chronic kidney disease: The most common secondary cause. Kidneys control fluid and sodium balance, damaged kidneys cause fluid retention and high BP.
• Renovascular hypertension: A constriction of the artery to the kidney activates the renin-angiotensin system leading to high blood pressure which can be very difficult to treat.
• Primary aldosteronism: When the adrenal glands make more aldosterone than normal, sodium is retained, and hypertension develops, usually at the expense of potassium.
• Hypo and hyperthyroidism can affect blood pressure; measure thyroid function in any patient who has weight changes, fatigue or palpitations and is hypertension; or in any woman of childbearing age who is taking certain anti-hypertension medications
• Obstructive sleep apnoea: In OSA, the repeated loss of oxygen during sleep causes a release of stress hormones and triggers a sleep apnoea-BP risk cycle   with the BP not dropping as it should during sleep.

How Untreated Hypertension Can Harm Your Body

In the term 'silent killer' 'silent' does not mean without symptoms, but without visible damage, at least until there is very visible damage. Over a period of years, high blood pressure slowly damages target organs, and only makes its presence known when a crisis occurs.

When hypertension is not treated, it causes damage in the following ways:

• Heart: Strain with increased resistance, thickening (hypertrophy) and eventually weakening. The risk of heart attack, heart failure and atrial fibrillation increases significantly.
• Brain: Hypertension is the one most modifiable risk factor for ischaemic stroke, haemorrhagic stroke and vascular dementia.

Kidneys: Elevated pressure over time leads to damage of the glomeruli (filters), which results in kidney disease. Hypertension and Kidney Disease work in a vicious cycle.

Eyes: Hypertensive retinopathy causes changes to the blood vessels of the retina that the doctor can detect during an eye exam and indicate cardiovascular risk.

Arteries: Early atherosclerosis (plaque formation) in all arteries, a heightened risk of peripheral arterial disease, aortic aneurysm, and arterial dissection

It can be prevented by blood pressure treatment. CDC data shows that when patients get their blood pressure under control, they are 35-40% less likely to have a stroke, 20-25% less likely to suffer a heart attack and more than 50% less likely to have heart failure.

Hypertension Treatment: Lifestyle First, Medication When Needed

The 2025 AHA/ACC guideline clearly states that lifestyle modification should be used for all grades of hypertension, and that drugs should be used when necessary, depending on stage of hypertension, cardiovascular risk, and other coexisting conditions like diabetes or kidney disease.

Lifestyle changes that have a measurable BP reduction

• Salt reduction target < 5g/day: Reduction in systolic BP of 5-6 mmHg
• DASH diet (High in vegetables, fruits and low fat dairy, reduced saturated fat): Reduction of 8-11 mmHg
• Walking with the aerobic exercise program: moderate BP reduction of 5-8 mmHg
• Weight loss of 5 kg in overweight patients: A decrease of ~5 mmHg
• Breaking up smoking: Reduces overall cardiovascular risk but not directly lowers resting BP.
• Alcohol reduction: Reduce to less than 14 units per week will result in a reduction of 3-4 mmHg
• Stressed management (structured): Slight decrease in blood pressure of 2-3 mmHg by yoga, meditation and sleeping improvement.

When consistently applied, these modifications can make the blood pressure of many people with Stage 1 hypertension (130 139/80 89) fall into the normal range without the use of blood pressure medication. They are used in addition to, not in lieu of, medications in patients with Stage 2 hypertension or in high-risk patients.

Antihypertensive Medication: The Main Drug Classes

If lifestyle changes alone are not enough or if BP is sufficiently elevated that waiting until lifestyle changes has occurred poses a high risk, a physician will begin hypertension medications. There are multiple classes of drugs that work:

• ACE inhibitors and ARB's: Inhibit renin-angiotensin system. Especially effective for diabetics and kidney patients. May cause a dry cough; an alternative is an ACE Inhibitor
• Calcium Channel Blockers: Loosen the muscle in the inner wall of the arteries. Effective in the Indian population (which are more "salt-sensitive"). Used to treat first-line or combination agents widely.Used to treat combination or first-line agents widely.
• Diuretics (thiazide type): Decrease fluid volume and blood vessel resistance. Highly effective, low-cost and recommended as initial therapy in most guidelines, frequently used in combination
• Beta-Blockers: Decrease heart rate and output. Useful for patients with concurrent heart failure or angina or arrhythmia.

The majority of people with hypertension will need at least two drugs to maintain a target blood pressure. This does not indicate failure; it's an example of the several mechanisms involved in hypertension. A best general physician in Jaipur will choose the right mix that is suitable for the entire clinical history of the patient and not just the most economical one.

Monitoring and followup: The part patients get wrong.

This is a chronic disorder that needs to be monitored and managed; it is not a one-time treatment. The BP needs to be measured at regular intervals to ensure the treatment is effective. The kidney function (creatinine, urea), electrolyte and fasting blood sugar should be monitored as it is influenced by the condition and some medications. Blood pressure changes and other conditions (comorbidity) will change over time and medication doses will be adjusted accordingly.

One of the most prevalent and most damaging failure patterns in hypertension management is having patients take their blood pressure medicine for a couple of months to feel better and then stopping because it's "normal now". The medication works, which brings the blood pressure back to normal. When it is stopped, it is almost always breathed back up. This is a dialogue which every GP in Jaipur should have with new patients who are diagnosed with hypertension.

Prevention: The Steps That Work Before Hypertension Develops

The ideal blood pressure treatment is one you never have to take. Primary prevention is possible and very effective for people who have normal or elevated (but not hypertension) blood pressure readings, as well as for those who have more than one risk factor.

Know your number: It takes about 2 minutes to get your blood pressure. Adults over the age of 25 should be familiar with their level of reading. If it was normal 3 years ago, that does not mean that it is normal today!

Systematically remove the salt: Majority of salt consumed in the Indian diet is during cooking, in pickles, papads, processed snack items and ready to eat food. Making some switch in your shopping habits makes a difference in your sodium intake!

Control weight around the waist: South Asian population has lower relative BMI to metabolic risk compared to Western populations. For women with overall BMI in normal range, a waist circumference of over 80 cm indicates a high risk, and for men over 90 cm.

Get enough sleep: Low sleep duration (<6 hours)> and sleep quality are independently associated with hypertension. Sleep apnoea is a largely unrecognised cause of treatment resistance and nocturnal hypertension in particular.

Control diabetes and cholesterol:  These don't directly lead to hypertension but can greatly increase cardiovascular risk when combined with hypertension. The risk of all three conditions combined is multiplicative, not additive.

Hypertension is a primary and chronic disease, not a secondary referral and is treated in the General Medicine department at Jaipur Vatika Hospital at Thikariya on the Jaipur-Ajmer Expressway. It is one of the most highly qualified chronic disease management by the best physician in Jaipur Dr. Amit Ghasil MBBS, MRCP London, having more than 10 years of experience in NHS UK practice.

• Initial assessment: Full clinical history, examination, basic blood tests (kidney function and electrolytes, fasting sugar, lipid profile, urine microalbumin), ECG and echocardiography co-ordination with the Cardiology department, to assess any existing organ damage.
• Structured treatment: Evidence-based choice of antihypertensive drugs, tailored to the patient's complete clinical profile (diabetes status, kidney function, other cardiac disease, tolerability to the different drugs)
• In-house monitoring: ALL hypertension monitoring tests done at the same time at NABL accredited pathology lab and results provided within a few hours (not days) of the visit.
• 24/7 availability: When a patient comes with blood pressure above 180/120, the best private hospital in Jaipur for hypertension management will be available round the clock, and JVH's general medicine and emergency department will be available. You don't need to worry about them closing when you have a blood pressure emergency.
• Lifestyle advice: Dietary counselling structured into steps, with specific measures to reduce salt intake in the Rajasthani diet, and exercise planning for various patient groups, plus weight management assistance.
• Comorbidity co-management: treatment is given for hypertension, diabetes and dyslipidaemia as one cardiovascular risk profile, rather than three separate conditions with three separate prescriptions from three separate specialists.

Conclusion

Hypertension is a silent, widespread, and deadly disease. It is the number one modifiable risk factor for heart attack, stroke and kidney failure, and, fortunately for most people who have it, it is not known. The problem is that many people know what high blood pressure symptoms are, but they don't take action when they read their blood pressure.

In the General Medicine department at Jaipur Vatika Hospital, residents of western Jaipur, Bagru, Dudu and the Ajmer Highway can get a blood test and know their blood pressure at the same visit, get expert advice from Dr. Amit Ghasil, who is a London-trained GP, and have direct access to the Cardiology and Nephrology departments for complex cases.
