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.

Pimples on skin is something we see on a day to day basis. Often, without even thinking much, we pop them. But did you know there is a 'Triangle of Death' on your face, where you should never pop a pimple?

Reacting to a video, Dr Sermed Mezher, a UK-based GP, and a health communicator who goes by @drsermedmezher on his Instagram handle says, "You should never pop pimples but it is even more important not to do it in a specific triangle of the face."

He reacts to a video where a boy shares his experience of popping a pimple on his face, which has left him in pain, and made him enable to use the side of his face with pimple. His face is now swelled.

What Is The Triangle of Death On Your Face?

Dr Mezher says that while it is named unscientifically, the area extends from the top of the nose to the upper lip. This is important because it drains the cavernous sinus. "So, we don't want bacteria to get into there," he notes.

Why Is Triangle Of Death A Dangerous Place To Pop Your Pimples?

“We naturally have bacteria on our skin, and every time we pop a pimple, we damage the skin barrier. That creates an opening for bacteria to move deeper into the skin. If those bacteria reach the cavernous sinus through the facial ‘triangle of death,’ it can cause a serious condition called cavernous sinus thrombosis," notes Dr Mezher.

He explains that this blood clot can lead to severe headaches, fever, pressure and pain behind the eyes, difficulty moving the eyes, and even eye swelling or bulging. "While it is usually treatable, prevention is far easier than cure, which is why popping pimples should be avoided."

According to Cleveland Clinic, this small segment of your face has a direct line to your brain, which is the cavernous sinus. It is a network of large veins located behind your eye sockets. Through this sinus, blood drains from your brain. This is why, any infection in this area, could a picked pimple or even a nose piercing gone wrong could impact your brain. Dermatologist Alok Vij, MD, tells Cleveland Clinic, "There is the possibility for a facial infection to become an infection that impacts the rest of your body."

Is The Triangle Of Death Really Fatal?

Well, as the name suggest, the triangle of death cannot actually kill you. Dr Vij says, "Thankfully, it is relatively unlikely. But, whenever there is a violation of the skin and interaction with bacteria, there is always a possible for infection, which can lead to greater health concerns."

In rare cases, an infection of the face can lead to septic cavernous sinus thrombosis, or a blood clot in your cavernous sinus. It could also lead to some life-threatening health issues, including:

• Brain abscess (pus that causes swelling of your brain)
• Brain infection
• Damage to your facial nerves, including paralysis of your eye muscles
• Meningitis
• Pneumonia
• Septic emboli (infected blood clots that travel through your bloodstream)
• Stroke

How To Deal With A Pimple In You Triangle Of Death?

• Apply a warm compress, use a clean cloth and apply it on the area for 10 to 15 minutes. Soak the clean cloth in warm water.
• Use a pimple patch or an overnight zit sticker that could soak up some of the drainage, in case your pimple has already opened.
• See a dermatologist.

In 2022, there were around 19,976,499 cancer cases diagnosed from around the world, notes the World Cancer Research Fund. Out of them, 10,311,610 were men, and 9,664,889 were women. In 2024, several reports say that there were over 19 million new global cases in that year. The cases of cancer are rising, so is there any way one can stay one step ahead of it?

While it is important to get screenings done frequently, especially if one has a family history of cancer, there could be certain red flags, one must look out for to book an appointment with oncology.

Here are the cancer red flag one must keep a look out for:

Persistent Fatigue

Persistent fatigue remains one of the most overlooked symptoms of oncology. This is not like a routine tiredness, this is a kind of exertion that stays despite rest, balanced meals, and time off. Data from 2022-24 shows that over 30% of early stage cancer patients reported unexplained fatigue prior to diagnosis.

Unexplained Weight Loss

Oncologists explain that over 40% of newly diagnosed gastrointestinal and lung cancer patients experienced weight loss. This could happen due to metabolic changes caused by tumors, which can alter energy absorption and consumption, often suppressing appetite and leading to a rapid loss of body fat.

When to see a doctor? If you have lost more than 5% of your body weight in under 6 to 8 weeks, it is important that you seek immediate medical attention.

Chronic Pain

If there is a pain that does not go away, it could be because of cancer. Many patients have complained of persistent pain as one of the fist symptoms of their cancers. This is particularly true for back pain, which is common in pancreatic or ovarian cancer. Bone pain too is common in metastasis, and pelvic pain is common in uterine or colorectal cancer.

Skin Changes

Not all cancers start inside the body, some also show up on the skin. These changes could be new moles, non-healing wounds, or changes in pigmentation. In fact, unusual rashes also signal changes like skin cancer.

Changes In Bowel And Bladder Habits

If you experiences changes in your bowel and bladder habits and find blood in your stool or urine, it is best to see a doctor. Colorectal, bladder and prostate cancers often start subtly. Before it becomes serious, keeping a track of your bowel and bladder habits could prevent the cancer from spreading.

Lump Or Thickening Of Body

While lumps could be benign, they are also one of earliest signs cancer. For instance, the early detection of breast cancer and testicular cancer are from lumps, which are observed while self examination. In fact, the early detection, thanks to self examination, has even increased by 22%.

Persistent Cough

While this may be a season of virus and flu, but if your cough does not go away, it may be a serious sign. If you find blood in your cough, see a doctor, take scans. If you are a smoker, you may be more prone to early stage throat cancer.

Headache That Does Not Go Away

There could be certain neurological issues, including a stubborn headache that does not go away. This may be an indication of a tumor in the brain.

If you have any of these stubborn symptoms, it is best to book a doctor's appointment and go for a screening.

Delhi's AQI on Tuesday morning seemed to be doing somewhat better than Monday morning. The AQI has brought some relief to the residents who had been dealing with 'severe' pollution levels, with visibility being hit. As per Tuesday's AQI, according to Central Pollution Control Board (CPCB), Delhi's air pollution stood at 381 AQI as of 6.30 am. This has placed the air quality in the 'very poor' category.

While it has become a habit of many to check AQI before stepping out of the house, how many of us actually understand what AQI really means?

Recently, Delhi's Chief Minister Rekha Gupta claimed that AQI and temperature are the same. At a summit hosted by a news channel, Delhi CM Gupta referred to AQI as "temperature".

Such statements could further lead to misconceptions, and add to everyday confusions. Health and Me is breaking down what AQI really means and why is it not the same as temperature.

How Air Quality Index Work And What It Means

As the Delhi CM claimed that AQI is like temperature and could be "measured using any instrument", is not true. Though it is understandable why such comparisons may have been drawn as you can easily check the AQI report on your phones, like we do with temperature.

However, in real sense, AQI or the air quality index is a tool used for communicating outdoor air quality and health. The AQI includes six-color coded categories, each of which corresponds to a range of index values. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

Air quality is made of dust and small particles like PM2.5 and PM10, along with gases like nitrogen dioxide from car exhaust, sulphur dioxide from factories, and carbon monoxide from vehicles. The levels are measured through specialized machines. In India, the standard of the machines are carried out by the Central Pollution Control Board or CPCB.

What Makes Delhi So Polluted?

As per a review of Delhi's air quality from 1990 to 2022, published in Sustainability (MDPI), an open access journal, these are the following sources of Delhi's Air Pollution:

• Transports emit around 10 to 30% of pollution. This includes all road, rail, and aviation modes and combustion of petrol, diesel, and gas.

• Dust make up another 10 to 30% of pollution. Dust from resuspension on the roads and construction activities.

• All industries, including small, medium, and large industries, including power plants and brick kilns lead to 10 to 30% of pollution.

• In summers, all residential activities, including cooking, lighting, and heating activities lead to 10% of pollution, whereas in winter, it makes up for 30%.

• Waste burning, including residential sides and landfills leads to 5 to 15% of pollution.

Power plants from outside the city leads to less than 7% of pollution. Dust storms contribute to less than 5% of pollution. Agricultural residue burning, which is a seasonal source of pollution leads to less than 3% of pollution, whereas firecrackers, another seasonal source, leads to less than 1% of pollution.
