How to Tell If Your Low Blood Pressure Is Dangerously Low? All On Living With Hypotension
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.
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.
Hypotension can result from many factors. Some of the factors that cause hypotension are as follows:
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.
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.
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:
Treatment of hypotension depends on its cause:
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.
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.
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.

As heatwaves have become more frequent and intense across the globe, health experts are increasingly warning that soaring temperatures affect far more than physical health. While dehydration, heat exhaustion, and heatstroke are common physiological effects of heatwaves, extreme heat can also take a significant toll on mental wellbeing.
HealthandMe spoke to Dr. Samant Darshi, Consultant - Psychiatrist & Neuromodulation Expert, Psymate Healthcare, Noida, about the psychological impact of extreme heat.
In hot weather, the human body constantly works to maintain a stable internal temperature. During periods of extreme heat, this process becomes increasingly challenging, placing considerable strain on both the body and brain.
Dr Darshi explains, “The high temperatures during heat waves can have a strong influence on not only physical but also the psychological state of people. The hot weather causes irritation, nervousness, stress, and frustration. Sleep disturbance associated with the hot weather only complicates the process of keeping a good mood.”
Living in higher temperatures is slowly becoming the new norm in several countries. With climate change driving longer and more intense heat events, understanding the psychological impact of extreme heat has become more important than ever.
Additionally, research has shown that prolonged exposure to heat can worsen stress, anxiety, irritability, and even increase the risk of severe mental health crises. Moreover, people's ability to think logically is affected by heat; memory, attention, and overall productivity decrease in extreme temperatures.
Dr Darshi says, “People with some pre-existing mental health conditions (depression, anxiety disorders, schizophrenia, etc.) can suffer from worsening their symptoms during prolonged heatwaves. The side effects of some medications that are used for the treatment of mental illnesses include the disturbance of the processes of thermoregulation in the organism.”
High temperatures can also disrupt sleep, hamper hormone levels, and affect neurotransmitters like serotonin and dopamine, which play a key role in regulating mood. Sleep deprivation, a common consequence of hot nights, can further intensify emotional distress, making people feel more anxious, irritable, or overwhelmed.
As temperatures soar, people generally avoid stepping out, becoming increasingly secluded. Lack of social interactions triggers the brain’s primal ‘survival threat’ alarm, which can lead to excessive stress, poor emotional regulation, and increased risk of anxiety and depression.
It especially affects older people and other vulnerable groups. Social isolation can cause psychological problems in terms of loneliness and depression. In extreme cases, prolonged exposure to heat causes aggression, self-harm, and other mental health crises.
While one has little to no control over the weather, certain measures can help reduce the mental strain caused by extreme heat:

Leptospirosis gained attention after its cases surged in Kerala recently. The infection has also been reported in Maharashtra, Gujarat, Tamil Nadu, and Karnataka. The bacterial infection typically spreads via contact with water or soil that has been contaminated by the urine of animals infected with leptospirosis, especially during floods.
As monsoons are right at our doors, know why it is important to detect and nab dangerous infections like leptospirosis early.
Leptospirosis is a potentially serious bacterial infection sometimes called the "rat fever" because it can cause symptoms similar to the typical symptoms of common viral infections, which may not be noticeable in the early stages. It is caused by the bacteria of the genus Leptospira that are excreted in the urine of infected animals, including rats, cattle, dogs, and pigs.
In the monsoon season, there is a risk of waterlogging and contaminated animal urine mixing with floodwater and soil. Infestation occurs through direct contact with contaminated water or mud on cuts or abrasions or on the mucous membranes of the mouth, nose, and eyes. Those involved in outdoor work, sanitation, farming, construction, or who are walking in flooded streets are especially at risk.
Health and Me spoke to Dr. Sundar Krishnan, Senior Consultant - Internal Medicine, KIMS Hospital, Thane, about how to tackle leptospirosis this monsoon.
Dr. Krishnan says, “In the early stages, it may have flu-like symptoms, and that makes early recognition challenging. Symptoms are sudden onset of high fever, chills, very severe headache, muscle pain especially in the calves and lower back, fatigue, nausea, vomiting, and red eyes.”
The expert also said that occasionally, the patient may also have abdominal pain or diarrhea. He also says it can escalate quickly to jaundice, kidney failure, difficulty breathing, meningitis, internal bleeding, or multi-organ failure and can require immediate medical care.
Dr. Krishnan recommends several prevention tips to tackle leptospirosis in monsoon:
If leptospirosis is diagnosed early and treated with antibiotics, recovery is much quicker, avoiding life-threatening complications. But if detection and treatment are delayed, the kidneys, liver, lungs, and even the brain may be affected.
The expert advises that people who are ill after being exposed to flood water and are facing fever or flu-like symptoms for more than two days should also seek medical help as soon as possible, informing their doctor about their flood water exposure.
Even though the risk of leptospirosis is high during the monsoon, the best way to steer clear of this infection is to educate the masses about its symptoms and prevention. Early clinical intervention can help de-escalate the situation promptly.

Headaches are one of the most common health complaints and are often caused by stress, lack of sleep, dehydration, excessive screen time, skipped meals, or other lifestyle factors. While most headaches are benign, experts said that frequent or unusual headaches should not be ignored, as they may signal an underlying medical condition that requires evaluation.
The experts told HealthandMe that paying attention to changes in headache frequency, pattern, and associated symptoms can help identify when medical attention is necessary.
According to Dr. Rajneesh Kummar, Vice Chairman & Unit Head, Neurology, Max Super Speciality Hospital, Dwarka, one of the most common concerns is increasing frequency.
“If someone who previously experienced occasional headaches starts getting them several times a week or finds that painkillers are needed more often than before, it is worth getting evaluated,” he told HealthandMe.
“People should seek medical attention if they have headaches more than 10 to 15 days a month, if the headaches are getting worse, or if they are beginning to interfere with work, daily activities, or quality of life,” added Dr. Praveen Gupta, Chairman, MAIINS, Marengo Asia Hospitals, Gurugram. He also noted that medication-overuse headaches can result from taking painkillers regularly, leading to a cycle of recurrent pain.

A change in the pattern of headaches should not be ignored. Dr. Kummar said a headache that feels different from what a person has experienced in the past, particularly after the age of 50, deserves medical attention. Headaches that wake a person from sleep, are worse in the early morning, or are associated with vomiting should also be assessed further.
Dr. Gupta advised prompt medical evaluation for people over the age of 50 who develop a new type of headache. He also recommends seeing a doctor if a person has a history of cancer, a weakened immune system, or develops a headache after a head injury.
The neurologists highlight several "red flag" symptoms that require urgent medical assessment. They advised immediate consultation if a headache is accompanied by

Dr. Kummar stated that many people worry that every headache is related to a brain tumor or another serious brain disorder. Fortunately, this is rarely the case.
However, persistent or unusual headaches should not be self-diagnosed, and timely consultation helps identify the cause and ensures appropriate treatment before the problem begins affecting quality of life, the expert said.
Dr. Gupta told HealthandMe that early diagnosis can help manage common neurological disorders such as migraines, cluster headaches, and chronic tension-type headaches. A thorough history, neurological examination, and imaging studies, when appropriate, can help determine the cause.
The experts emphasize that if headaches are becoming more frequent, changing in patterns, or affecting daily life, it is time to consult a neurologist. Early diagnosis can provide relief, prevent complications, and improve overall quality of life.
