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.

In a global first, India's drug regulator has approved a fully synthetic cannabidiol (CBD) therapy for the treatment of mild to moderate anxiety disorders, marking a significant milestone in cannabinoid-based medicine.

The Central Drugs Standard Control Organisation (CDSCO) has granted regulatory approval to Zenara Pharma, the manufacturing partner of Leiutis Pharmaceuticals, to produce a synthetic cannabidiol oral solution (150 mg/ml). The prescription-only therapy is intended to be used alongside cognitive behavioural therapy (CBT) for managing mild to moderate anxiety disorders.

In a statement, Leiutis Pharmaceuticals said the approval follows a successful Phase III clinical trial conducted in India under CDSCO guidelines. A Phase IV post-marketing study will now be carried out to further evaluate the therapy.

World's First Fully Synthetic CBD Therapy

Leiutis noted that "this is the first regulatory approval anywhere in the world for a fully synthetic cannabidiol oral solution for anxiety disorders".

K. Chandrasekhar, CEO and Managing Partner of Leiutis Pharmaceuticals LLP, said the approval is the result of nearly a decade of cannabinoid research, including the development of a proprietary synthetic cannabinoid manufacturing process, novel drug-delivery technology, and extensive preclinical and clinical studies.

“Developed entirely in India and protected by patents in key markets, this approval is a significant milestone for our innovation pipeline, paving the way for next-generation cannabinoids. We thank the Government of India, clinical investigators, researchers and study participants who made it possible,” Chandrasekhar said.

What Is the New CBD Therapy?

The newly approved medicine contains a fully synthetic cannabidiol (CBD) active pharmaceutical ingredient (API), meaning no cannabis plant material is used in its production.

The therapy combines:

• A synthetic cannabidiol API developed by Biophore India Pharmaceuticals.
• Leiutis Pharmaceuticals' proprietary nanodispersible drug-delivery platform to improve absorption.
• Manufacturing by Zenara Pharma at facilities compliant with CDSCO, US FDA and European regulatory standards.

Biophore has also filed a United States Drug Master File (US DMF) for the synthetic CBD manufacturing process, reflecting internationally recognized quality standards.

Why This Approval Matters

The approval comes at a time when anxiety disorders are rising sharply in India. According to a recent analysis from the Global Burden of Disease Study published in The Lancet, anxiety disorders in India increased by 123.5% between 1990 and 2023.

The prevalence rose from 2,591.9 cases per lakh population in 1990 to 5,792.8 cases per lakh in 2023, driven largely by increasing rates of anxiety and depression.

What Is CBD?

Cannabidiol (CBD) is one of the naturally occurring compounds found in hemp and cannabis plants. Unlike THC, it does not produce intoxicating effects.

CBD has been studied for several potential therapeutic uses, including:

• Reducing anxiety symptoms
• Relieving chronic pain
• Improving sleep
• Managing certain seizure disorders
• Reducing inflammation

The newly approved product, however, uses synthetic CBD, which is produced entirely in a laboratory rather than extracted from the cannabis plant. Synthetic CBD offers a highly consistent and contaminant-free formulation, helping standardize dosing and quality.

Does CBD Have Proven Medical Benefits?

CBD already has established medical use in certain seizure disorders in some countries and continues to be investigated for a range of other conditions, including anxiety, chronic pain, inflammation and schizophrenia.

CBD is generally well-tolerated, but some users may experience mild side effects like drowsiness, reduced appetite, or diarrhea. Side effects are often due to interactions with other medications.

For many women, the last day of treatment feels like crossing a finish line they have been running toward for months. There is relief, there is gratitude, and there is often a quiet sense of disbelief that it is actually behind them. But finishing treatment is not really the end of the journey. It is the start of a new chapter—one we call survivorship—and it deserves just as much care and attention as everything that came before. Understanding what lies ahead can make all the difference between living in fear and living well.

Follow-Up Care Must Continue

Recovery does not mean walking away from the hospital. In the first few years after treatment, survivors are usually asked to return for follow-ups. The reason behind this is simple: if cancer ever returns, catching it early gives the best chance of treating it successfully. Or in many cases it a good habit to keep a check and boost confidence to the survivors.

Impact of treatment

What often surprises many women is that the impact of cancer treatment may continue even after active treatment ends. Recovery is a gradual process, and experiences can vary significantly from one individual to another depending on the type of cancer, treatment approach, and overall health. In terms of breast cancer, some women may continue to face physical, emotional, or lifestyle-related challenges during survivorship, while others may require ongoing therapies or follow-up care to reduce the risk of recurrence. What must always be remembered is that these issues cannot be addressed in silence. Open communication between the woman and her treatment team may allow problems to be sorted out in time, with the proper support being provided.

Emotional Health Deserves Equal Attention

Healing is not only physical. Many survivors carry a constant worry about whether the cancer will come back, while others feel strangely lost once the busy routine of treatment falls away. These emotions are completely natural and nothing to be ashamed of. Speaking to a counsellor, joining a support group, or simply being honest with the care team can lighten the burden enormously.

Healthy Habits Support Recovery

The choices made every day genuinely shape long-term health. Eating plenty of vegetables, fruits, and whole grains, and staying active with something as simple as a thirty-minute walk most days, makes a real difference. Keeping to a healthy weight is especially important, because carrying excess weight is linked to a higher chance of the cancer returningi. Cutting back on alcohol and staying away from tobacco add further protection.

Adjusting to Physical Changes

The body changes after cancer and coming to terms with this takes time. Worries about appearance and intimacy are entirely understandable, and they are worth raising during clinic visits, because often there are practical ways to help.

Be an Informed Advocate

No one understands a patient's body better than the patient herself, which is why every survivor should feel empowered to ask questions. Before treatment ends, it is wise to request a survivorship care plan. This is a summary of the treatment received, together with a clear schedule for future check-ups. Such a document becomes an invaluable guide, both for the survivor and for any doctor she may see in the years ahead.

Looking Ahead

Survivorship is rarely a straight line. There will be good days and harder ones, moments of confidence and moments of doubt. With regular check-ups, a few sensible habits, and the support of people who care, life after breast cancer can be every bit as rich and full as before—sometimes even more so. Because in the end, the goal of cancer treatment was never just to help women survive. It was always to help them truly live.

More than 57 million people worldwide are living with dementia, a number expected to triple to over 152 million by 2050. While there is still no cure, growing evidence suggests that healthy lifestyle changes can help improve brain health and preserve cognitive function in older adults at risk of dementia.

A major study published in The Lancet suggests that adopting healthy lifestyle habits can significantly improve memory and thinking skills in older adults at risk of dementia.

The study found that a culturally adapted, structured lifestyle program delivered across 11 Latin American countries produced meaningful improvements in cognitive function over two years. Participants in the intensive program showed 55 per cent greater improvement in overall cognition than those who received general health advice.

Lead author Lucia Crivelli, principal investigator at Fleni, a neurological institute in Buenos Aires, Argentina, said culturally adapted lifestyle interventions can be successfully implemented across diverse communities and "deliver cognitive benefits" for people at risk of dementia.

"Addressing multiple lifestyle factors can positively impact brain health and may eventually be combined with emerging drug therapies to reduce cognitive decline and dementia risk," added Heather M. Snyder, senior vice president of medical and scientific relations at the Alzheimer's Association.

What Did The Study Find?

The clinical trial enrolled 1,065 adults aged 60 to 77 years at increased risk of cognitive decline across 12 sites in Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, the Dominican Republic, Ecuador, Mexico, Peru and Uruguay.

Participants were randomly assigned to one of two groups. The Systematic Lifestyle Intervention (SLI) group received ongoing coaching, supervised exercise, personalized nutrition counselling, cognitive training and regular monitoring of cardiovascular risk factors. The Flexible Lifestyle Intervention (FLI) group received general lifestyle recommendations through periodic health education sessions without continuous coaching or supervision.

The structured program combined supervised exercise, a brain-healthy MIND diet, computer-based cognitive training, regular monitoring of blood pressure, blood sugar and weight, and social engagement activities designed to encourage accountability and interaction.

To improve participation, the intervention was adapted to local cultures. Exercise sessions incorporated familiar activities such as salsa and tango, while nutrition counselling focused on regionally available foods including avocado, quinoa, açaí, chia seeds, pumpkin seeds and aguaymanto.

After two years, participants in the structured intervention experienced:

• 55 per cent greater improvement in overall cognitive performance than those in the flexible intervention group.

• The largest gains in memory.

• Significant improvements in executive function, including planning and decision-making.

• Faster processing speed.

The cognitive benefits were consistent regardless of participants' age, education level, ethnicity or genetic risk for Alzheimer's disease.

The authors noted that while the program improved performance on cognitive tests, it did not determine whether the intervention prevents dementia. They said longer-term follow-up is needed to establish whether these cognitive improvements ultimately reduce the risk of developing the disease.

What Is Dementia?

Dementia is an umbrella term used to describe a significant decline in mental function that is serious enough to affect everyday life. It commonly impacts memory, thinking, and reasoning skills. Dementia itself is not a single disease but a collection of symptoms caused by underlying conditions such as Alzheimer’s disease or vascular dementia.

Common signs include

• memory problems,
• confusion,
• difficulty finding words,
• changes in mood or behavior,
• trouble completing familiar tasks.
