Low blood pressure, also known as hypotension, is usually considered a sign of good health and low risk for cardiovascular disease. However, there are times when persistently low blood pressure or a sudden drop can be a sign of an underlying health issue that needs medical attention. Knowing when low blood pressure becomes a problem can help ensure timely intervention and proper care.

Blood pressure readings consist of two numbers:

Systolic pressure (the top number) indicates the pressure in your arteries when your heart pumps blood. Diastolic pressure (the bottom number) reflects the pressure in your arteries while your heart is resting between beats.

The normal reading is usually 120/80 mmHg or less. Hypotension is clinically defined as having blood pressure readings less than 90/60 mmHg. In some patients, low blood pressure will have no adverse health consequences and therefore does not need to be treated. In extreme cases, however, it can limit the flow of oxygen and nutrients to vital organs, resulting in potentially life-threatening complications, such as shock.

Causes of Low Blood Pressure

Hypotension can result from many factors. Some of the factors that cause hypotension are as follows:

• Insufficient fluid intake or excessive fluid loss can lead to decreased blood volume and hence hypotension.
• An injury or internal bleeding may result in hypotension. This happens because blood pressure becomes significantly reduced.
• Some hormonal changes along with the increased blood requirement during pregnancy also causes hypotension.
• Issues like heart failure or arrhythmias can impair blood circulation and result in low blood pressure.
• Certain drugs, including diuretics, antidepressants, and blood-pressure-lowering medications, can induce hypotension.

Symptoms of Hypotension

While low blood pressure may not always cause symptoms, it can sometimes be associated with:

- Dizziness or fainting

- Fatigue and weakness

- Blurred vision

- Nausea

- Confusion or difficulty concentrating

- Shallow breathing

- Palpitations

If the person experiences these symptoms, with the recorded blood pressure reading, the medical services have to be consulted.

Types of Low Blood Pressure

1. Orthostatic Hypotension: This is a kind of hypotension that appears as a result of decreased blood pressure when a person is standing up from lying down or sitting position and primarily affects elderly people.

2. Postprandial Hypotension: This is a drop in blood pressure after eating, more common in older people.

3. Neurally Mediated Hypotension: It is triggered by standing for long periods. This type can affect younger people and is associated with miscommunication between the brain and heart.

When Is Low Blood Pressure Dangerous?

There is no such thing as a universal threshold for very low blood pressure, but a blood pressure reading below 90/60 mmHg can be dangerous and require prompt medical assessment if accompanied by symptoms of fainting, confusion, or shortness of breath. Sudden falls in blood pressure may point to potentially serious underlying causes, which can include:

• Internal bleeding
• Sepsis (severe infection)
• Allergic reactions

Management and Treatment

Treatment of hypotension depends on its cause:

• Hydration Drinking more water can help against dehydration-related hypotension.
• Compression Stockings: These can improve circulation and reduce blood pooling in the lower limbs.
• Dietary Changes: Increasing salt intake under supervision can help increase blood pressure
• Medication Changes: The physician may need to reduce dosages of some medications or replace prescriptions.

For more severe cases, physicians might also administer fludrocortisone or midodrine to increase blood pressure. Shock from hypotension should be treated promptly to ensure proper function of organs.

Can Hypotension Cause Fatigue?

Chronic fatigue syndrome has also been associated with low blood pressure. Prolonged tiredness, despite adequate rest, may require reassessment of blood pressure levels. Fatigue secondary to hypotension will impact functionality and thus requires assessment and treatment of the cause.

When to Seek Medical Care

If your blood pressure readings are low consistently and without symptoms, you probably have nothing to worry about. If you do have symptoms like dizziness, fainting, or confusion, you need to go to the doctor. Blood pressure checks are usually conducted regularly. Once you are aware of your own normal baseline, you will know right away when there is something wrong.

Lifestyle Tips That Support Normal Blood Pressure

1. Other than directly treating hypotension, a healthy lifestyle overall would promote balanced blood pressure levels.
2. Exercise regularly; it promotes cardiovascular health and can help regulate blood pressure.
3. Focus on nutrient-dense foods rich in iron, B vitamins, and electrolytes to support circulatory health.
4. Excessive alcohol consumption dehydrates the body and lowers blood pressure.
5. Practices like yoga and meditation can help maintain a healthy blood pressure range.

Fasting for three hours before bed can significantly improve heart health and reduce the risk of coronary artery disease (CAD) as well as other chronic conditions, an Arteriosclerosis, Thrombosis, and Vascular Biology study suggests.

While many believe that diet plans such as intermittent fasting or time-restricted eating can help reduce their weight, researchers at Northwestern University have found that not eating three hours before going to sleep can reduce overnight blood pressure by nearly four percent, heart rate by five percent and strengthen overall heart rhythms.

This can help reduce overall strain on the heart which lowers risks for conditions like hypertension and CAD. Additionally, the scientists also discovered a drop in blood sugar levels, improved glucose tolerance and insulin sensitivity.

Participants who underwent glucose tests also showed better insulin release which tend to stabilize during the day. Additionally, an improved heart rate also lowered nighttime cortisol, which helped in metabolic balance.

Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine and chief of sleep medicine in the department of neurology at Feinberg and corresponding author said of the results: "It's not only how much and what you eat, but also when you eat relative to sleep that is important for the physiological benefits of time-restricted eating."

The study authors also noted: "Extending overnight fasting duration by three hours in alignment with sleep improved cardiometabolic health in middle-aged/older adults by strengthening coordination between circadian- and sleep-regulated autonomic and metabolic activity.

"This sleep-aligned time-restricted eating approach represents a novel, accessible lifestyle intervention with promising potential for improving cardiometabolic function."

Coronary Artery Disease: The Silent Killer

Despite being as a common heart disease, coronary artery disease (CAD) develops over years and has no clear signs and symptoms apart from a heart attack. The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.

Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead chest pain (angina), shortness of breath and ultimately, heart attacks.

Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis can increase the risk of developing CAD.

Treatment options may include medicines and surgery. Eating a nutritious diet, getting regular exercise and not smoking can help also prevent CAD and the conditions that can cause it.

Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.

Strokes: A Rising Crisis In India

Additionally, heart strokes are also one of the leading global health burdens, causing significant deaths and disability worldwide, including in India. Compared to Western countries, stroke also tends to occur at a younger age and is associated with a higher case fatality rate in the country.

One in seven stroke patients in India are young adults aged below 45 years, with hypertension leading as the major risk factor, according to a study by the Indian Council of Medical Research (ICMR).

The Global Burden of Disease Study 2021 identified hypertension, air pollution, tobacco smoking, high cholesterol, increased salt intake, and diabetes as the leading risk factors of stroke.

Incidence of stroke is increasing significantly in low- and middle-income countries (LMICs), especially in India, due to population growth, aging, and greater exposure to risk factors.

Often called the stress hormone, cortisol is produced by your adrenal glands, located on top of the kidneys. The hormone plays a critical role in keeping you healthy and maintaining your energy as well cardiovascular health.

Cortisol is a necessary tool for survival and naturally peaks in the morning to help you wake up and drop at night to help you sleep. While the body has a system in place to maintain hormone levels, issues arise when cortisol levels stay chronically high, meaning your body is constantly in "fight-or-flight" mode.

This can happen due to long-term stress, certain medical conditions (like Cushing’s Syndrome), or the prolonged use of steroid medications.

However, Dr Suman Agrawal, a renowned Oxford University certified nutritionist and qualified fitness expert has shared how "Shin-Kokyu”, a technique used by Japanese samurais before a battle exercise can help reduce cortisol by 80 percent

Step One: Box breathing method:

• Inhale for four seconds through the nose while the tongue touches the palate
• Hold for four seconds with abdominal muscle tension
• Exhale for four seconds through the mouth, lips pursed
• Pause for four seconds with complete relaxation

Step Two: Hara point

Place three fingers below the navel with medium force & hold throughout the breathing. There’s a cluster of vagus nerve endings there. It’s like a button in the body.

Step Three: Gaze into nowhere

Look straight ahead and defocus your gaze as if you are looking through a wall for three minutes. This time span is equal to 12 breathing cycles which is the minimum time needed to reboot the nervous system.

Symptoms Of High Cortisol Levels

When cortisol is elevated for a long time, the body’s systems get overwhelmed. Common symptoms include:

• Physical Changes: Rapid weight gain, particularly around the abdomen, face (moon face) and the back of the neck (buffalo hump).
• Skin Issues: Thinning skin, easy bruising, and pink or purple stretch marks on the abdomen or thighs.
• Muscle & Bone: Weakness in the arms and thighs, muscle loss and an increased risk of bone fractures (osteoporosis).
• Metabolic Signs: High blood pressure, high blood sugar and a strong craving for sugary or fatty foods.
• Emotional & Cognitive: Persistent anxiety, irritability, mood swings, depression, brain fog and difficulty concentrating.
• Sleep & Energy: Chronic fatigue, feeling tired even after a full night's sleep and insomnia.

Health Risks of Chronic High Levels

If high cortisol levels are left un-addressed for an extended period, they can lead to serious health complications, including:

• Cardiovascular Disease: Chronic hypertension and damage to blood vessels increase the risk of heart attack and stroke.
• Type 2 Diabetes: Persistent spikes in blood sugar make it difficult for the body to manage insulin effectively.
• Suppressed Immune System: Chronic cortisol elevation can weaken immune response, making the body more susceptible to infections and slowing down wound healing.
• Mental Health Disorders: Long-term exposure is strongly linked to chronic anxiety and major depressive disorders.
• Digestive Issues: It can disrupt gut health, exacerbating conditions like IBS, bloating, and indigestion.

In a world fascinated by trendy superfoods, many traditional and nutrient-rich foods have been overlooked despite offering remarkable health benefits. From ancient grains, pulses to sprouts, these foods provide essential vitamins, minerals, protein and bioactive compounds that support digestion, immunity, bone health, and overall wellbeing.

However while many are aware of the benefits of fruits such as blueberries and grains such as oats, here are some important superfoods you need to incorporate in your diet:

1. Quark/ Curd

Quark, a German word for curd, has many benefits including being protein-rich which helps with muscle maintenance and repair, making it especially useful for older adults at risk of age-related muscle loss, known as sarcopenia.

The milk-based item is also low in calories and fat, providing nutrients without excess energy which also helps with weight management.

Apart from this, quark aids in gut health as it has same digestive bacteria as yogurt also known as probiotics. Probiotics are beneficial as they increase good bacteria in the intestine while keeping check on harmful bacteria. Moreover, they also helps absorb vitamins and minerals better.

Another benefit of consuming quark regularly is its high calcium content that is essential for supporting bone and teeth health such as preventing conditions like osteoporosis.

2. Prunes

Prunes are highly beneficial for digestive health as they are rich in fiber and contain sorbitol, a natural sugar alcohol that helps the gut absorb water and acts as a gentle, natural laxative.

They are also packed with protective plant compounds called polyphenols which function as antioxidants to reduce oxidative stress, lower inflammation and support overall cellular health.

Regular prune consumption can also help maintain bone mineral density, particularly in postmenopausal women by reducing the risk of osteoporosis. In addition, prunes provide important vitamins and minerals, including potassium, magnesium, copper, and Vitamin K, all of which support heart function, strengthen bones and assist enzymatic processes in the body.

Despite their sweetness, prunes are known to have a low glycemic effect due to sorbitol. This allows them to lower glycemic sugar levels in the body and increases overall blood sugar at a lower rate than other fruits, making it a safe option for diabetic patients to consume.

3. Blackcurrants

Blackcurrants are an exceptional source of Vitamin C, especially higher than oranges, and can support immune function, the body's fight against infections and aids in collagen production to maintain skin elasticity as well prevent scurvy, bleeding gums, fatigue and joint pain.

They are also rich in antioxidants called anthocyanins, which help neutralize free radicals, reduce oxidative stress and potentially lower the risk of chronic heart as well as gut-related diseases. The polyphenols in blackcurrants contribute to vascular health by improving blood vessel function and maintain healthy blood pressure.

In addition, blackcurrants are a good source of potassium, which is essential for heart muscle contraction and maintaining fluid balance. Additionally, the whole fruit provides fiber, which aids digestion, blood sugar control and cholesterol management.

4. Sprouts

Harvested at the plant’s most concentrated growth phase, sprouts pack high levels of bioactive compounds, known to be crucial in removing harmful toxins and reducing overall chronic inflammation.

Moreover, broccoli sprouts are rich in glucoraphanin, which the body converts to sulforaphane, a sulfur-containing compound that supports the liver's process of detoxification and has anti-inflammatory properties

Sprouts also provide a concentrated source of vitamins, minerals and antioxidants in a small, versatile form, making them easy to incorporate into meals. They can be eaten raw for full nutrient absorption or cooked thoroughly to minimize the risk of food-borne illnesses such as salmonella or E. coli.

While the vegetable is beneficial for most people, pregnant women, elderly and immuno-compromised individuals should avoid raw sprouts due to higher infection risk.

5. Liver

Called “nature’s multivitamin,” liver is known to be packed with high-quality protein, iron, and B Vitamins, making it a valuable source of essential nutrients.

It is also rich in Vitamin A and iron, which supports vision, immune function and cell growth and prevents iron deficiency, a common issue among menstruating women.

Liver also provides a concentrated source of other nutrients, especially B12, B6, riboflavin, folate which are important for energy metabolism, red blood cell production and nervous system health. Experts recommend consuming chicken liver to maximize on its benefits.

However, due to its very high Vitamin A content and purine levels, it should be consumed in moderation to avoid toxicity and prevent triggering conditions like gout.

6. Emmer

Emmer, an ancient form of wheat that retains its seed coat, is rich in fiber, vitamins, minerals and antioxidants as well as carbohydrates.

This allows it to support digestion, heart health and sustainable energy release, making it a valuable component of a balanced diet. Given its nutty flavor, emmer can be used as a substitute for rice or couscous, helping to diversify meals and supporting overall health and metabolic balance.

7. Peas

Peas, especially traditional varieties like carlin and marrowfat, are a good source of nutrients yet often overlooked despite sharing many of the same benefits as beans, a well-known top-tier superfood.

Carlin peas are rich in fiber and a good source of plant-based protein, supporting healthy digestion, blood sugar regulation, and muscle maintenance. They are also known to be versatile enough to include in snacks or meals.

On the other hand, marrowfat peas provide similar nutritional value and can be enjoyed in ways similar to avocado, a nutrient-dense superfood, adding both protein and fiber to the diet.
