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.

Heart disease remains the leading cause of death in India, often affecting people nearly a decade earlier than in Western populations.

Recent cholesterol management recommendations from the American Heart Association (AHA) and related global guidelines emphasize aggressive control of LDL cholesterol — the so-called “bad cholesterol.” For Indians, these recommendations carry particular importance.

Studies consistently show that South Asians have a higher tendency for premature coronary artery disease. Even individuals who appear relatively lean may have underlying metabolic risk factors such as insulin resistance, abdominal obesity, and elevated triglycerides. Because of this inherent susceptibility, the same cholesterol levels that may appear “borderline” in Western populations can translate into a significantly higher cardiovascular risk in Indians.

What Does The New Guidelines Say

The newer guidelines shift the focus away from merely treating cholesterol numbers to assessing an individual’s overall cardiovascular risk.

Factors such as diabetes, smoking, blood pressure, family history of early heart disease, and age are considered together. If a person falls into a higher-risk category, doctors now recommend lowering LDL cholesterol more aggressively than before.

For people who already have established heart disease, the goal is particularly strict. LDL cholesterol is ideally reduced to levels below 55 mg/dL. Achieving such targets often requires not only lifestyle changes but also medications such as statins, and in some cases, newer therapies that further lower cholesterol levels.

How Indians Can Prevent Heart Disease

For Indians without diagnosed heart disease, prevention becomes the key message. Regular screening after the age of 30–35 years is increasingly advisable, especially if there is a family history of heart disease or diabetes. Diet also plays a central role: reducing trans fats, limiting refined carbohydrates, increasing fibre intake, and maintaining a healthy body weight can significantly influence cholesterol levels.

Equally important is regular physical activity. Even 30 minutes of brisk walking most days of the week can improve lipid profiles and reduce cardiovascular risk.

The key takeaway is simple: Indians develop heart disease earlier and often at lower cholesterol levels.

The newer AHA recommendations reinforce the need for earlier screening, individualized risk assessment, and more proactive cholesterol management to prevent future heart attacks.

A sudden bone fracture that seems out of proportion to the injury could sometimes signal an underlying life-threatening condition. Doctors say that while most fractures are caused by accidents or age-related bone weakness, certain cancers can damage bones and make them fragile enough to break with minimal force.

While this is still relatively uncommon compared to injuries or diseases such as osteoporosis, experts stress that unusual fractures should not be ignored.

How Cancer Can Weaken Bones

Bones are living tissues that constantly rebuild and repair themselves however, some cancers can start directly in the bone which are known as primary bone cancers., such as osteosarcoma, Ewing’s sarcoma, and chondrosarcoma. These cancers damage bone structure and make it fragile.

However, more often the problem comes from cancers that begin in other organs and then spread to the bones, also known as metastasis, which means cancer cells travel from their original location to another part of the body.

According to Dr Rakesh Kr Agrawal, Senior Consultant and Head of Radiation Oncology at Andromeda Cancer Hospital in Sonipat, cancers such as breast, prostate, lung, kidney, and thyroid frequently spread to bones. The spine, pelvis, ribs, and thigh bones are particularly common sites.

When cancer spreads to these areas, it can destroy bone tissue or create weak spots, increasing the chance of fractures.

Blood Cancer And Bone Damage

Bone marrow is the soft tissue inside bones where blood cells are produced. In multiple myeloma, abnormal plasma cells grow uncontrollably and interfere with normal bone rebuilding.

This often leads to lytic lesions, which are small areas where bone tissue has been destroyed. These weak spots can cause bones to break easily, sometimes without any obvious injury.

Doctors estimate that up to 80 percent of people with multiple myeloma already have fractures or severe bone damage when the disease is first diagnosed.

Warning Signs To Watch For

Apart from the type of cancer, doctors also say the context of a fracture matters. A break after a serious fall is usually straightforward but certain patterns may raise concern.

One major warning sign is a fracture after minimal trauma. This means a bone breaks even though the force involved was very small, such as stepping awkwardly or lifting something light.

Persistent bone pain is another signal. Pain that lasts for weeks, becomes worse at night, or appears before a fracture occurs may suggest that the bone was already weakened.

Swelling around the bone or a lump near the fracture site should also be evaluated carefully. These signs may indicate that the bone had an abnormal growth or tumor before the damage.

Doctors also look for systemic symptoms, which are symptoms affecting the whole body rather than just one area. These may include unexplained weight loss, fatigue, anemia, frequent infections, nausea or constipation.

Why Early Investigation Matters

Experts emphasize that most fractures are still caused by common conditions like osteoporosis or accidental injuries. Cancer is a much rarer explanation.

However, when something about a fracture seems unusual, doctors may recommend additional tests. These can include imaging scans such as X-rays, CT scans, or MRI scans to examine the bone more closely. Blood tests or specialised panels may also be done to look for conditions like multiple myeloma.

Early detection is important because many cancers can be treated more effectively when diagnosed sooner. Doctors advise adults, particularly those in middle age or older, to seek medical advice if a fracture happens with very little force or is accompanied by persistent pain or swelling.

In many cases the explanation will still be something simple like bone thinning. But identifying rare causes early can make a significant difference in treatment and recovery.

As specialists point out, paying attention to unusual symptoms and seeking timely evaluation is often the first step toward protecting long-term health.

Blood sugar spikes are dangerous as it could trigger inflammation, oxidative stress, and damage blood vessel linings. The most dangerous, risk of type 2 diabetes, cardiovascular diseases and cognitive decline. When people think of blood sugar spikes, they think of food, carbohydrates or sugary food items that should be avoided. However, there are other things too that are not food, but could spike your blood sugar.

NHS doctor, Dr Amir Khan, who is a general physician with NHS England, resident doctor on ITV's Lorraine and Good Morning Britain, and host of the No Appointment Necessary podcast on his Instagram channel highlighted five non-food related reasons that could spike your blood sugar.

"Did you know your blood sugar can spike even if you haven't had a single bite to eat?" He starts his video with this disclaimer and goes on to say, "Let me share five surprising things that can raise your blood sugar and why it might not always be a bad thing."

Five Reasons Beyond Food That Could Spike Your Blood Sugar Levels

Stress

Dr Khan shares that stress triggers a rise in cortisol levels that activates the body's fight-or-flight response. This signals the liver to release stored glucose into the bloodstream to provide a quick boost of energy. This thus leads to a surge of glucose in blood and leads to the rise of blood sugar levels.

"When you're stressed, your body releases cortisol, the fight or flight hormone that tells your liver to release stored glucose to give you energy. Great if you're running from a tiger, less helpful if you're just stuck in traffic. Remember, chronic stress equals chronic glucose spikes and that is not good for long-term health,” he explains.

Poor Sleep

He also highlighted that even a single night of poor sleep could increase insulin resistance, which means glucose stays in the bloodstream for longer duration and could lead to elevated blood sugar levels. He said that chronic sleep deprivation could raise the risk of developing type 2 diabetes even in people who try to maintain otherwise a healthy diet.

"One bad night, your body becomes more insulin resistant. That means glucose hangs around in the blood for longer and over time, poor sleep can increase your risk of type 2 diabetes, even if you try your best to eat well," he says.

Exercise

To many people's shock, he says exercise could temporarily spike blood sugar. "Number three, exercise. Yes, even the good stuff. Certain types of exercises, especially intense or resistance training, can temporarily raise your blood sugars. Why? Well, again, it's your body releasing glucose for fuel, but really importantly, long-term, exercise improves insulin sensitivity, meaning lower blood sugars overall. So, this is not a bad spike,” he explains.

However, he does point out that it is not a bad thing. He notes that certain forms of physical activity, especially intense or resistance training could prompt the body to release more glucose in bloodstream to fuel the muscles. However, he also points out that regular exercise improves insulin sensitivity over time and helps the body regulate sugar more effectively.

Infections And Illnesses

“When you're fighting off a bug, your immune system has to ramp up, and that comes with a glucose surge. It's your body's way of fueling the immune response. People living with diabetes often notice higher blood sugar levels when they're unwell. That's totally normal and they may have to adjust their medication accordingly,” explains Dr Khan.

What this means is that when your body is fighting off infection, it releases more glucose in your bloodstream that works as a fuel for your immune system. This is why people with diabetes often notice higher blood sugar when they are unwell. However, he points out that this is body's normal response to combat illness.

Hormones

"Ladies, this one's for you because it's mainly around your periods or the menopause. In the second half of your menstrual cycle, that's the luteal phase, progesterone levels rise. This can make your cells more insulin resistant, meaning higher blood sugars. And of course, in perimenopause and the menopause, estrogen levels decline, and that comes with insulin sensitivity dropping. So you become more resistant to insulin, leading to more frequent spikes in blood sugar. That's why women in their 40s and 50s may notice weight gain, fatigue, or brain fog which can be linked to blood sugar shifts.”

Dr Khan notes that hormonal fluctuations during different phases of menstrual cycle could also influence blood sugar levels. Higher progesterone during luteal phase could make cells more insulin resistant. When estrogen is declining during perimenopause or menopause, it could further reduce insulin sensitivity.

Dr Khan concludes, “So remember, not all blood sugar spikes are bad. Context matters. But if you're seeing high readings and you're not sure why, it's always worth talking to your doctor and it’s not always about what you're eating.”
