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.

Oral cancer cases are on the rise because of tobacco chewing, smoking, alcohol consumption, poor oral hygiene, and delayed medical attention. Many people ignore small red or white patches, which are early warning signs of cancer and should never be overlooked. There is an average delay of six months in cancer diagnosis, which is the reason patients are diagnosed with stage 3 and 4 cancers.

Dr Prathamesh Pai, Senior Consultant Head and Neck Surgical Oncologist, Gleneagles Hospital, Parel, Mumbai, explained the difference between red and white patches in the mouth and what they may indicate about your health.

Red vs White Patches in the Mouth

White patches inside the mouth are called leukoplakia, while red patches are known as erythroplakia. Both can occur on the tongue, gums, inner cheeks, or floor of the mouth. Though both need equal attention, red patches are more dangerous, with a higher risk of being cancerous in comparison to white patches. Red patches in the mouth indicate severe abnormal cellular changes, which can develop into precancerous conditions or cancer. Around 60% to 80% of erythroplakias are diagnosed as early-stage cancer on biopsy.

What is erythroplakia?

Erythroplakia is a fiery red, well-defined patch in the mouth. These lesions are velvety in appearance. They often appear on the floor of the mouth or the retromolar trigone (the area behind the wisdom teeth). Red patches often go unreported, as they are mistaken for traumatic mouth ulcers caused by hard foods or dental irritation.

If a red patch does not heal within two to three weeks, it should raise concerns about cancer. Besides the duration, patches that bleed on touch, are painful while eating, are associated with a burning sensation, difficulty swallowing, loosening of teeth, or voice changes should be investigated. Tobacco users should be even more mindful. Ignoring persistent red or white patches can allow the disease to progress silently.

So, make sure to seek immediate help and consult a doctor. For anyone presenting with red or white patches, the doctor will carry out a physical oral examination and a biopsy, in which a small tissue sample is taken from the patch for evaluation. A CT scan and MRI may also be advised, depending on the location of the patch and other clinical features.

Why early detection of cancer matters

Remember, early detection of cancer is curable. Treatment is also less extensive, often involving minor intraoral surgery and preservation of speech and swallowing functions. As the cancer stage advances, surgery may require the removal of parts of the cheek, jaw, or tongue, as well as postoperative radiotherapy. This affects the face and neck and hampers important functions such as eating, speaking, and swallowing. This has major implications for quality of life. Treatment can also be a financial burden, especially for younger patients.

Take charge of your life. Lead a happy, healthy life. Avoid tobacco, alcohol, and other addictions. Visit your dentist regularly and maintain good oral hygiene. Prevention is better than cure. In the case of any non-healing ulcers in the mouth, swelling in the neck, altered speech or swallowing, or altered bowel habits for more than two weeks despite treatment, do visit a doctor. Remember, early detection of cancer is curable.

New Delhi's weather is fluctuating sharply, with Western Disturbances driving bouts of intense heat and sudden pre-monsoon showers. The city is currently hovering in the mid-30s°C but is also bracing for a return to scorching heat, with maximum temperatures forecast to climb into the low to mid-40s°C this week.

Such weather fluctuations can play a significant role in triggering migraine attacks, said Dr. Vivek Kumar, Principal Director - Neurology, Max Super Speciality Hospital, Patparganj.

Weather Factors That Can Trigger Migraines

Speaking to HealthandMe, Dr. Vivek noted that many components of weather are reported to affect migraine. These include:

• Barometric pressure
• Humidity
• Temperature
• Seasons

Dr. Kumar explained that a drop in atmospheric pressure, often seen before storms, can create a pressure imbalance between the environment and the sinuses or inner ear, stimulating nerves and leading to headaches.

"Rapid temperature changes, as well as exposure to extreme heat or cold, can also trigger migraine episodes," he said.

Similarly, both high humidity and very dry air have been associated with the onset of migraine symptoms. Bright sunlight and intense sun exposure, particularly when reflected off surfaces such as snow or water, are also recognized migraine triggers.

How Does The Weather Trigger Migraines?

According to Dr. Kumar, weather changes can affect brain chemistry by influencing serotonin levels, a neurotransmitter involved in migraine development. They may also contribute to inflammation or pressure differences within the sinuses.

Further, the expert noted that seasonal transitions can be particularly challenging.

"Spring and summer may trigger migraines because of heat and allergens, while winter's cold and dry air can also contribute to headaches and sinus discomfort," he said.

Notably, weather is often only one factor among several. Allergies during spring or viral illnesses during autumn may also combine with environmental changes to trigger headaches, Dr. Kumar stressed.

Migraine is also frequently mistaken for a sinus headache because the symptoms often overlap.

Dr. Kumar noted that migraine attacks can cause forehead and facial pressure, as well as nasal congestion or a runny nose. Unlike migraine, however, sinus infections may be accompanied by fever.

He explained that migraine can activate nerves in the face, a phenomenon known as cranial autonomic activation, which can create sensations of nasal blockage and congestion.

While weather changes are difficult to avoid, monitoring weather forecasts may help people prepare for potential triggers. Preventive treatment may also reduce sensitivity to environmental changes and allow greater freedom in daily activities.

Tips To Prevent Migraine

Dr. Kumar advised:

• Keeping a migraine diary for at least 90 days to help identify specific weather-related patterns associated with attacks.
• Treating migraine attacks early when weather-related triggers are suspected. Early treatment can shorten the duration of an attack and prevent symptoms from becoming severe.
• Maintaining adequate hydration, particularly during hot weather or physical activity. Carrying water when outdoors can help compensate for fluid loss through sweating.
• For those sensitive to bright sunlight, staying indoors during peak daylight hours may be beneficial. When outdoor exposure is unavoidable, protective sunglasses or hats can help reduce glare and light sensitivity.

Pancreatic cancer is one of the most feared diseases, and it causes thousands of lives to be wasted away due to this fatal disease. According to the Population-Based Cancer Registries (PBCRs) managed by the Indian Council of Medical Research (ICMR) and the IARC Global Cancer Observatory (GLOBOCAN), about 22,982 Indians have pancreatic cancer every year.

On the other hand, the American Cancer Society's US SEER Pancreatic Cancer Stat Facts shows the annual number of cases is 67,530. Thus, any lead to resisting cancer is good news for the world. Recently, a research team from Stony Brook Medicine and Luisa Escobar-Hoyos of Yale School of Medicine, led by Kenneth Shroyer and Natalia Marchenko, found an important fact to fight the fatal disease.

The study investigated the role of Keratin 17 (K17) and found that the protein can be a driver of chemoresistance to gemcitabine. It is often used to treat various types of cancer. The study shows that the K17 can act as a target for the development of novel treatments.

They discovered that the protein is a key driver of chemoresistance to gemcitabine, an agent used to treat a wide range of cancers, including advanced tumors of the pancreas, lungs, and breast.

How New Pancreatic Cancer Drug Daxorrasib Can Help You?

Daxaronrasib is a daily oral pill that has demonstrated statistically significant and clinically meaningful improvements in progression-free survival (PFS) and overall survival (OS) compared with standard intravenous chemotherapy.

Described as a multi-selective inhibitor of RAS(ON) proteins, it is the first investigational drug in a new class of RAS inhibitors designed to target a broad spectrum of cancer-causing RAS mutations.

The drug works by blocking KRAS signalling proteins that drive tumor growth.

Daraxonrasib is the first drug. It works by pairing up with a protein called cyclophilin A inside cells, acting like a molecular glue, glomming onto the mutated protein.

Pancreatic cancer is considered one of the most RAS-dependent cancers, with more than 90 per cent of patients carrying tumours driven by RAS protein mutations. Similar RAS-targeting drugs are also being developed for pancreatic, lung, and colon cancers.

The findings were presented at a plenary session of the American Society of Clinical Oncology’s meeting in Chicago on May 31 and simultaneously published in the New England Journal of Medicine.
