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.

A two-year-old boy from Bristol, UK has died from a rare heart disease, known to mostly affect children with only flu-like symptoms, on January 8.

Hudson Martin had been diagnosed with Kawasaki disease when he was seven months old and was placed on lifelong medication including aspirin and blood thinners to reduce the risk of clots. Since then, he had been living a normal and happy life, according to father Damien Martin.

He told Bristol Live: "You’d never know anything was wrong from pictures or videos. He bounced off everything. He loved climbing, dancing, music, he was a proper daredevil."

But days before his third birthday, he suddenly collapsed while playing at home. Despite being given CPR by paramedics for an hour, his heart did not restart and he passed away.

“They did absolutely everything they could,” Damien said. "His heart just wouldn't come back."

What Is Kawasaki Disease?

Also known as mucocutaneous lymph node syndrome, Kawasaki disease causes inflammation in the walls of small to medium-sized blood vessels that carry blood throughout the body which can damage to the heart and blood vessels, mostly in children younger than five years old.

When this happens, the heart doesn't work as well to pump blood to the body and could burst (coronary artery dilation and aneurysms). It also causes swelling in the lymph nodes and mucous membranes inside the mouth, nose, eyes and throat.

Apart from a 102.2 degrees Fahrenheit (39 degrees Celsius) fever that can last for five days, children with Kawasaki may also experience some or all of the following symptoms:

• Rash on the main part of the body or in the genital area
• Swelling and redness of their hands and feet
• Irritation and redness of the whites of their eyes
• Swollen lymph glands in the neck
• Irritation and inflammation of the mouth, lips, and throat

It remains unknown what causes Kawasaki disease in children and if it affects adults.

Diagnosis involves ruling out other diseases that cause the same symptoms which include:

• Scarlet fever
• Juvenile rheumatoid arthritis
• Stevens-Johnson syndrome (a disorder of the mucous membranes)
• Toxic shock syndrome
• Measles
• Some illnesses caused by ticks, such as Rocky Mountain spotted fever

Is It Curable?

While this non-contagious disease can be treated with a mixture of antibodies given through the veins (intravenous immunoglobulin) and aspirin, it remains uncurable. Doctors may also advice steroids if intravenous immunoglobulin is not effective.

After receiving treatment for Kawasaki disease, most children recover fully and long-term follow-up care remains unnecessary. However, children who have suffered through aneurysms or other complications related to the disease will need lifelong monitoring with a cardiologist.

Cases of scabies, a highly contagious skin condition caused by microscopic mites, continue to remain higher than normal across England this winter, according to the latest surveillance data. Recent findings from the Royal College of General Practitioners’ Research and Surveillance Centre indicate that scabies has been spreading more widely than expected over the past few months, with infections steadily increasing through autumn and winter.

Overall, reported cases have stayed above the usual five-year average, with the sharpest rise recorded during the final four months of last year, particularly across northern regions of the country. With scabies infections continuing to climb, concerns are growing around which treatments are safe to use, especially when it comes to children.

What Is Scabies?

Scabies is caused by a microscopic parasite known as Sarcoptes scabiei. This mite burrows into the top layer of the skin to lay its eggs, triggering severe itching and a red, spotty rash that often becomes more intense at night. Although the mites are too small to be seen easily, measuring less than half a millimetre, the body reacts to their saliva, eggs, and waste, leading to an allergic response.

Scabies spreads through prolonged skin-to-skin contact and can affect people of all ages. According to the NHS, it is most commonly transmitted through close household contact, including between partners, family members, people living together, and during sexual activity.

How Is Scabies Spreading In The UK?

UK Health Security Agency surveillance data shows that scabies cases reported through sexual health services remained relatively stable before the COVID-19 pandemic, but numbers began rising sharply from 2022 onwards. Diagnoses increased from 3,393 cases in 2023 to 4,872 cases in 2024, marking a 44 per cent rise.

• London accounted for roughly one-third of all cases recorded in 2024.
• The steepest percentage increase was seen in the North East, where reported cases nearly doubled.
• Young adults aged 20 to 24 made up 41 per cent of diagnoses, while those aged 25 to 34 accounted for 31 per cent.

Scabies UK: What's Behind The Surge In Cases?

Both the UKHSA and the British Association for Sexual Health and HIV (BASHH) suggest several reasons could be driving the surge:

• Increased social interaction and physical contact following the pandemic, after years of reduced mixing.
• Greater awareness of scabies and more testing taking place at sexual health clinics.
• Overcrowded housing and the ongoing cost of living crisis, which may delay access to prompt treatment.

Experts also caution that the actual number of cases is likely much higher, as the available data only reflects diagnoses made in sexual health settings.

Scabies UK: Can Ivermectin Treat Scabies In Children Safely?

Ivermectin is an oral antiparasitic medicine used to treat scabies by paralysing the mites. It offers a systemic alternative to topical creams and is often considered in cases that are widespread, severe, or involve institutional outbreaks. Because the drug does not kill scabies eggs, a second dose is usually required after seven to fourteen days to target newly hatched mites.

According to the Centres for Disease Control and Prevention, ivermectin is generally well tolerated, improves treatment compliance compared to creams, and has been widely used in mass drug administration programmes, though repeat dosing is important due to its limited effect on mite eggs.

Despite its broad use in programmes targeting conditions such as river blindness, intestinal worms, and scabies, ivermectin has traditionally not been recommended for children weighing under 15 kilograms, largely due to limited safety data. However, researchers revisited this concern following a systematic review and meta-analysis that suggested the drug could be safe even in children weighing as little as 11 pounds.

In a double-blind clinical trial, researchers assessed the safety, effectiveness, and pharmacokinetics of ivermectin in young children with scabies. A total of 240 children weighing between 11 pounds and under 33 pounds in The Gambia, Kenya, and Brazil were randomly assigned to receive ivermectin at doses of 200, 400, or 800 micrograms per kilogram alongside a placebo cream, or placebo tablets alongside permethrin cream. Blood samples were collected on days 0, 3, 7, 10, and 14 to monitor biochemical markers, drug levels, and blood health.

Ivermectin: Only One Serious Adverse Event

The findings showed that ivermectin was effective in treating scabies, with just one serious adverse event reported. This involved a temporary increase in liver enzymes, which returned to normal levels within 32 days. All other side effects possibly linked to the treatment were mild, resolved on their own, and were similar to those seen in children weighing more than 33 pounds.

“Outcomes from the Ivermectin Safety in Small Children trial will hopefully provide greater reassurance that ivermectin can be safely used in children weighing less than 15 kilograms,” said lead study author Kevin Kobylinski, PhD, an honorary visiting research fellow at the University of Oxford with the Mahidol Oxford Tropical Medicine Research Unit in Bangkok, in an ASTMH press release.

England is recording higher-than-normal scabies infections this winter. Health authorities have cautioned that the condition, caused by microscopic mites known as Sarcoptes scabiei that tunnel into the skin, spreads quickly through close physical contact and often leads to severe itching and irritation. Data from the Royal College of General Practitioners’ Research and Surveillance Centre shows scabies is circulating more widely than usual in England, with cases increasing through the autumn and winter months.

Scabies UK: What Is Scabies?

Scabies is caused by the Sarcoptes scabiei mite. These tiny parasites burrow beneath the skin where they survive, feed and lay eggs. The presence of the mites triggers an allergic reaction in the skin, resulting in an itchy rash. Scabies passes easily from one person to another, particularly among people living in close quarters.

If one member of a household is infected, doctors usually advise checking and treating other family members and close contacts at the same time, according to the Cleveland Clinic.

Scabies UK: What Are The Early Symptoms Of Scabies?

Early signs of scabies include intense itching, which is often worse at night, along with a pimple-like rash, small blisters, and thin, irregular lines on the skin known as burrows. These symptoms commonly appear between the fingers, on the wrists, elbows, armpits, waist and genitals. According to the National Health Service, these reactions occur due to the body’s response to the mites and their eggs beneath the skin.

Symptoms do not usually appear straight away and may take three to six weeks after the initial infection to develop. However, people who have had scabies before may notice symptoms within a few days. Typical signs include severe night-time itching and small bumps, blisters or burrow-like tracks on areas such as the hands, wrists, elbows, nipples, genitals and waist.

In more severe cases, the skin may become thickened, rough and scaly. Among children and older adults, scabies can also affect the scalp, face or the soles of the feet.

Scabies UK: Are There Different Types Of Scabies?

Yes, scabies exists in several forms beyond the classic type. These include:

• Crusted (Norwegian): This form is more likely to affect people with weakened immune systems. It causes thick crusts over large areas of skin and can involve millions of mites, compared with the 10 to 15 mites typically found in classic scabies.
• Nodular: More commonly seen in children, this type affects areas such as the genitals, groin or armpits. Firm, raised lumps may persist even after the mites have been eliminated.

Scabies UK: How Is Scabies Treated?

Scabies is usually treated successfully with prescribed medicated creams and lotions called scabicides, along with careful hygiene measures. To avoid reinfection, clothes, bedding and towels should be washed at high temperatures and tumble-dried or ironed. Items that cannot be washed should be sealed in a bag for at least three days, as the mites cannot survive without contact with human skin.

Professor Michael Marks, a professor of medicine at the London School of Hygiene and Tropical Medicine and former chair of the International Alliance for the Control of Scabies, said the rise in cases may be linked to delays in accessing medical care and gaps in identifying and treating close contacts, which can allow the infection to continue spreading.
