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.

Three simple lifestyle changes, such as regular physical activity, cutting down sedentary time, and improving sleep duration, may significantly boost your brain's cognitive abilities and reduce the risk of dementia later in life, according to a new study.

Dementia is a neurodegenerative condition affecting an estimated 55 million people globally. It is characterized by a decline in memory, thinking, and social abilities.

Together, the three simple lifestyle changes cut down the risk of late-onset dementia by 25 percent.

Published in the open-access journal PLOS One, the systematic review and meta-analysis of over 69 prospective cohort studies involving millions of cognitively healthy adults aged 35 and above showed the potential benefits of lifestyle behaviors such as regular physical activity, cutting down sedentary time, and improving sleep duration.

According to the Alzheimer’s Association, a person’s overall risk for developing Alzheimer’s disease—the most common form of dementia—is about 11 percent. However, the study found that with the simple suggested lifestyle changes, the average person’s risk decreases to approximately 8 percent.

The study emphasized that people do not need elaborate and expensive longevity hacks to stay mentally sharp as they age.

The reduction is “fairly comparable to the effect sizes sometimes seen with medications for chronic diseases,” said Akinkunle Oye-Somefun, a researcher at York University in Toronto, who led the study, NBC News reported.

Sitting For Long Periods Worst For Your Brain

The findings showed that avoiding sitting for longer periods had the greatest effect and can have a long-term benefit for the brain.

Sitting for more than eight hours a day increased dementia risk by almost 30 percent, at the same time being regularly active, even just going for a walk every day, decreased dementia risk by an average of 25 percent.

Long sitting hours can also spike a person’s risk of other conditions such as cardiovascular disease, diabetes, and obesity, all of which in turn raise dementia risk.

Getting between seven and eight hours of sleep each night also had a greater benefit on the brain.

The risk of dementia increased by 18 percent among those who slept less than seven hours, while sleeping more than eight hours per night also raised the risk of the neurodegenerative disease by 28 percent.

Importantly, moderate physical activity “offsets dementia risks even when other risk factors are present,” said Oye-Somefun, NBC News reported.

However, “many people assume that being physically active cancels out the harm of sitting for long periods. It doesn’t,” Oye-Somefun said. “We shouldn’t do one of these things alone; we should do them all.”

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.

These symptoms usually worsen over time and are not considered a normal part of ageing. Although there is no cure, treatment options can help manage symptoms, and early diagnosis plays an important role in care planning.

It was during the COVID-19 pandemic that Annabelle Gurwitch, an American author, actress, and television host, developed a "a little persistent cough".

Suspecting it to be a COVID symptom, Annabelle went for a check-up. Her doctor alarmingly informed her about something suspicious on her lungs. Soon after, an X-ray and a biopsy confirmed her diagnosis of stage 4 cancer.

But, here's the catch. Annabelle is a non-smoker. She also lived a healthy lifestyle and exercised every day, and felt like she was in really good health, besides the persistent little cough.

HealthandMe spoke to health experts to understand how a persistent cough signals the risk of lung cancer.

If you, too, are a non-smoker who is leading a healthy lifestyle and has no medical conditions other than a persistent cough, then you must visit your doctor right away, advised the experts.

"A persistent cough can be an early warning sign of lung cancer, especially when it shows specific features rather than behaving like a routine respiratory illness," Dr Sameer Khatri, Principal Director - Medical Oncology, Max Super Speciality Hospital, Patparganj, told HealthandMe.

The doctor noted that the cough becomes suspicious when it persists beyond three weeks without a clear cause or fails to respond to standard symptomatic treatment such as cough syrups, bronchodilators, etc.

"A change in a pre-existing smoker’s cough—for example, becoming more frequent, severe, or different in character—is particularly important. In non-smokers, a new, unexplained chronic cough should not be ignored," Dr. Khatri said.

Certain associated symptoms further strengthen the suspicion of cancer. The most significant is hemoptysis, the coughing up of blood or blood-stained mucus, even if minimal.

Other red flags include

• unintentional weight loss,
• chest pain,
• breathlessness,
• hoarseness,
• recurrent pneumonia in the same lung region.
• age >40 years,
• smoking history, occupational exposures.

Persistent cough: TB Vs Lung Cancer

Persistent cough also signals the risk of tuberculosis (TB) -- the world's most deadliest infectious disease. Understanding the differences between these two causes is critical for early diagnosis and timely treatment.

Dr Seema Jagiasi from MOC Cancer Care Center told HealthandMe that the cough in TB may sometimes produce blood-tinged phlegm, but it is usually associated with signs of infection, such as fatigue and a general feeling of illness.

TB is more common in younger populations and in individuals with weakened immunity or poor living conditions.

"In contrast, a cough associated with lung cancer tends to be more insidious. It may start as a dry, persistent cough that gradually worsens over time. Unlike TB, it may not initially present with fever or infection-related symptoms," the doctor explained.

One of the key differences lies in progression and response to treatment.

TB is treatable with a course of antibiotics, and symptoms often improve within weeks of starting therapy. However, a lung cancer-related cough persists or worsens despite routine medications.

Dr Jagiasi emphasized that any cough lasting beyond three weeks, especially when accompanied by alarming symptoms, should not be ignored.

"Early investigations, such as chest imaging and further diagnostic tests, can help distinguish between the two conditions," the doctor said.

While both TB and lung cancer may present with a persistent cough, their underlying causes, associated symptoms, and progression differ significantly.

The health experts called for more awareness and the need for timely medical evaluation for the effective management of the disease.

Irish Actor Michael Patrick, known for his significant role in Game of Thrones, has sadly passed away at the young age of 35.

Sharing the news in a post on social media platform Instagram, his wife Naomi Sheehan shared that Michael Patrick (whom she fondly calls Mick) died after a years-long battle with Motor Neurone Disease.

"Last night, Mick sadly passed away in the Northern Ireland Hospice. He was diagnosed with Motor Neurone Disease on 1st February 2023. He was admitted 10 days ago and was cared for by the incredible team there. He passed peacefully, surrounded by family and friends," Naomi said.

Calling Michael a "titan of a ginger-haired man", she said that “Words can’t describe how broken-hearted we are".

Naomi called Michael an "inspiration to everyone."

What Is Motor Neurone Disease (MND)

MND is a rare and progressive neurodegenerative disease. According to NHS UK, it causes muscle weakness that gets worse over a few months or years. It's usually life-shortening, and there's currently no cure, but treatment can help manage the symptoms.

Symptoms of MND include:

• stiff or weak hands
• weak legs and feet
• twitches, spasms, or muscle cramps (where muscles painfully tighten).

It makes everyday tasks such as climbing stairs or gripping objects difficult.

As the disease advances, patients may develop difficulties with breathing, swallowing, and speech, along with changes in mood or personality. In later stages, walking and movement can become extremely limited.

Treatment of MND

About 1,500 people are diagnosed with MND each year, yet treatment choices remain scarce. Only a small proportion of patients currently qualify for therapies that target the disease process itself.

MND can be difficult to diagnose in the early stages. But as the symptoms get worse, it can usually be confirmed.

Tests used to help diagnose MND include:

• blood tests
• tests to check how well your nerves are working
• an MRI scan to help rule out other conditions that affect the brain and nerves

1. Amyotrophic lateral sclerosis (ALS): Early symptoms include muscle weakness in the arms and legs can cause you to trip and drop things.

2. Progressive bulbar palsy (PBP): It mainly affects muscles in the face, throat, and tongue, causing slurred speech and problems swallowing.

3. Progressive muscular atrophy (PMA): It causes weakness in the hands.

4. Primary lateral sclerosis (PLS): Leads to weak legs, sometimes with other symptoms, including speech problems.

Common treatment options for MND include:

• physiotherapy and exercises to help with muscle weakness and stiffness
• dietary advice to help you maintain weight
• speech and language therapist to help with talking
• Cognitive behavioral therapy (CBT) to help cope with emotions and feelings, such as anxiety and depression.
