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.

The U-WIN (Universal Immunization Win) platform has been transformative and has helped India tackle the concerning burden of zero-dose children, said Dr NK Arora, an immunization expert and member of the National Technical Advisory Group on Immunisation in India (NTAGI).

In an exclusive conversation with HealthandMe during World Immunization Week 2026, Dr Arora, Executive Director of The INCLEN Trust International, traced the journey of the U-WIN portal and explained how it has strengthened vaccine uptake in the country.

U-WIN is a digital platform and app to help people find vaccination centers near their residences, manage vaccination appointments at health facilities, and maintain vaccination records.

Dr Arora noted that the U-WIN portal created a digital ecosystem that played a critical role in registration, appointment scheduling, vaccine tracking, and real-time monitoring.

The Origin Of U-WIN

U-Win was launched in October 2024 and is available in 12 languages, including English.

Dr Arora, also the chair of the COVID-19 and HPV vaccine working group, shared that during the deadly COVID pandemic in 2020—around July—it became very clear that to vaccinate 140 crore people, some kind of IT platform is needed that will track individuals who had been vaccinated, especially when they needed their second dose, and later, booster doses.

“Everything started somewhere around July 2020, and by January 2021, we had the Co-WIN platform. By mid-April, things were streamlined. The platform gives us a long list of individuals who have been vaccinated. It also helps to know who has been left out of the vaccination.

“It is like a registry of human beings who are getting immunized. And we could send reminders, we could send certificates, and we can also tell the individual when to get their second and third dose,” the expert said.

He noted that as COVID became less intense toward the end of 2021, serious discussions began on using the same platform for routine immunization. This is where the concept of U-WIN came in 2022. It has now been piloted and is gradually being used.

U-WIN: Closing the Gap For Missed and Zero-Dose Children

The UWIN now has the mechanism to ensure that immunization is completed for everyone who registers. One user can register up to 10 people in one mobile number, including citizens/guardians, pregnant women, infants (0-1 years), children (1-7 years), and adolescents (7-19 years).

“The key issue is that tracking provides two or three important inputs. First, it ensures that everyone is getting vaccinated and that it is not dependent on memory. There is a proper record—whether a person or child has received vaccines and what their current status is, including whether the schedule is complete,” Dr Arora said.

“Second, one of the main reasons for missing or delaying the next dose was that mothers often did not remember. Fathers contributed very little to this process, but they also became involved because of the reminder system,” he added.

Another important role of U-WIN is tackling the so-called zero-dose children—those who have never been vaccinated.

“About 4–5 per cent of our eligible population falls into this category, meaning they have not received even the first pentavalent dose. On the face of it, 4–5 per cent may not seem like a huge problem. But when we look at the absolute numbers—out of 26 million—it translates into a very large number, which we cannot afford to miss. So tracking helps identify these children through the micro-plan system”.

“When a child is vaccinated, we know when boosters are due—at one and a half years, then at five years. But none of us remembers this. Even among well-informed parents, this is often forgotten. This system helps address that gap,” Dr. Arora said.

Further, when the same individual becomes eligible for vaccines like HPV—typically between 9 and 14 years—there is again a gap that needs to be addressed.

Certification is another benefit, as it creates a documented process, particularly for programs like oral polio vaccination.

Dr. Arora highlighted that in case of any future pandemic-like situation that requires repeated vaccinations, “we have a mechanism in place”.

“This IT platform has truly transformed the system. There is also a lot of discussion about using similar platforms for TB patients, pregnant women, and other flagship programs like non-communicable diseases. So, for India, digitalisation is at its best when we talk about U-WIN.”

Summer can invite a plethora of health problems in children. Moreover, dehydration is commonly seen when the body loses more fluids than it takes in. It is important to understand that early or subclinical dehydration can present as fatigue, irritability and reduced appetite, often going unnoticed by parents. Hence, parents need to detect the signs and symptoms of dehydration in children and seek timely help. Parents should follow the vital measures suggested by experts and safeguard their well-being.

Are children more prone to dehydration in a heatwave?

Dr Tushar Parikh, Senior Consultant Neonatologist and Head of Department at Motherhood Hospital, Kharadi, Pune, in an interaction with Health and Me, spoke about dehydration in children and how parents can identify it promptly.

“As temperatures rise during the summer months, dehydration becomes a common yet often overlooked problem in children. Dehydration occurs when the body does not have enough fluids to function properly. The causes can include inadequate fluid intake, sweating, prolonged outdoor play, and illnesses such as fever, vomiting and diarrhoea,” Dr Parikh explained.

Children are at a greater risk of dehydration as fluid loss occurs quickly through sweat. Severe dehydration is easier to identify, but early or ‘subclinical’ dehydration often goes unnoticed, silently affecting a child’s health and behaviour. Parents may assume that their child is simply tired or irritable due to the heat, but these could be early warning signs of fluid imbalance. Dehydration is often the last thing that comes to mind. However, it is frequently considered a minor issue in children. Subclinical dehydration refers to mild fluid loss that does not show obvious signs, such as extreme thirst, but still affects the body.

What are the symptoms of dehydration in children?

Dr Parikh stated that many children exhibit symptoms such as tiredness, irritability and poor appetite. They may also complain of headaches, feel dizzy, or show reduced concentration while studying. Another important sign is decreased urination or darker urine, which often goes unnoticed. Over time, if not addressed, this mild dehydration can impact energy levels and mood, and may become severe, requiring hospital admission. Hence, parents must take charge of their child’s health and seek timely attention even for mild dehydration.

How can parents help children when they are dehydrated?

Dr Parikh shared some simple tips that can help beat dehydration in childre. The expert said that dehydration can be prevented in children by encouraging them to drink water regularly. Children should ideally consume at least 2–3 litres of water daily, along with coconut water, buttermilk and fresh fruit juices to stay hydrated. Parents can also include foods such as watermelon, oranges and cucumbers, which help maintain hydration. It is advisable to limit junk, oily, canned and processed foods. Children should avoid playing outdoors during peak heat hours. Parents should dress their children in light, loose cotton clothing, which helps reduce sweating. Monitoring urine colour and frequency can be a simple way to assess a child’s hydration status. Parents should adhere to these tips to prevent dehydration in children.

Do you see your elderly loved ones pausing and quietly struggling every time they eat? In many households, a slight difficulty in swallowing—known as dysphagia—is often brushed aside as normal ageing or eating too fast.

Speaking to HealthandMe, doctors warned that this seemingly harmless symptom should not be ignored, as it could be cancer of the esophagus.

"When food repeatedly feels stuck in the chest, or swallowing becomes difficult, it may not be ageing at all. It could be an early warning sign of a serious condition, including esophageal cancer," said Dr. Surender Kumar Dabas, Chairman - Manipal Comprehensive Cancer Centre and Onco Robotic Surgeries, Manipal Hospital.

Esophageal cancer is a growth of cells that starts in the esophagus. The esophagus is a long, hollow tube that helps move swallowed food from the back of the throat to the stomach for digestion.

"Esophageal cancer typically remains silent during its initial phases, and the inability to swallow is one of the most typical warning signs. With the expansion of the tumor, the food pipe has the potential to get narrowed, which obstructs the smooth passage of food into the stomach. In case an individual constantly feels that something gets stuck in the mouth, one has to see a doctor and have a proper examination," added Dr. Hemkant Verma, Consultant - Surgical Oncology, ShardaCare-Healthcity.

Although difficulty swallowing is usually the first sign people notice, the body sends out other quite signals too. This includes:

• Food sticking in the chest or throat: A sensation that food is not going down smoothly and feels stuck after swallowing, especially with solid foods.

• Gradual difficulty in swallowing: Initially struggling with solids like roti or rice, and gradually facing difficulty even with semi-solids or liquids.

• Frequent choking or coughing while eating: This may indicate that food is entering the airway instead of the esophagus

• Unintentional weight loss: Dropping weight without even trying, mostly because eating has started to feel like a difficult chore.

• Chest pain: A persistent discomfort behind the breastbone that is not relieved with an antacid

• Vomiting or coughing up blood: A serious sign that the lining of the food pipe is irritated or damaged and needs immediate attention.

Treatment For Esophageal Cancer

Esophageal cancer is a malignant tumor in the food pipe, and primarily affects people over the age of 55.

The doctors also warned of lifestyle choices that may predispose one to esophageal cancer. This includes tobacco use, alcohol consumption, chronic acid reflux, obesity, and bad diet choices.

While early diagnosis is quite important to enhance the success of treatment, patients often tend to postpone seeking medical treatment for such symptoms, resulting in late diagnosis and poor outcomes.

The first step in diagnosis is usually an endoscopy, where a camera is used to check for any unusual growths. If a tumor is found, a biopsy is taken.

Upon biopsy confirmation, a staging workup is required, usually in the form of a PET-CT scan.

Treatment typically involves a multidisciplinary approach consisting of radiation and chemotherapy followed by surgery. The surgery is known as esophagectomy, where the diseased part of the tube is removed, and the remaining part is reconnected to the stomach. If detected early and treated properly, the disease is curable.
