Cold sores are a common and often frustrating skin issue. While they may look like harmless blisters, cold sores are actually caused by the herpes simplex virus (HSV).

What Causes Cold Sores?

Cold sores are caused by the herpes simplex virus (HSV), which comes in two types: HSV-1 and HSV-2.

HSV-1 is the primary cause of cold sores, usually appearing around the mouth.

HSV-2 generally causes genital herpes but can also lead to cold sores.

While the appearance of cold sores caused by both HSV-1 and HSV-2 can look similar, their locations tend to differ. However, it is possible for HSV-1 to cause sores on the genitals and for HSV-2 to appear on the mouth.

How Do Cold Sores Spread?

Cold sores are highly contagious and can spread easily. The virus can be passed on through:

• Kissing or skin contact
• Sharing food, drinks, or cosmetics (such as lip balm)
• Oral sex, which can spread both cold sores and genital herpes

Even when a cold sore isn’t visible, the virus can still be spread through close contact. This makes prevention and management key to reducing outbreaks and the risk of infecting others.

Once someone contracts HSV, it stays in the body for life. While the virus remains dormant most of the time, it can reactivate and cause new sores, especially during periods of:

• Stress
• Illness
• A weakened immune system

Unfortunately, there’s no cure for the herpes virus, but the symptoms can be managed.

Symptoms of Cold Sores

Cold sores don’t just appear out of nowhere. Before the sore is visible, you may notice a tingling or burning sensation around the lips or face, which can occur several days before the sore forms. This is the best time to begin treatment to shorten the outbreak.

When a cold sore does appear, it often looks like a red, raised blister filled with fluid. The blister can be painful to touch, and there may be more than one. Cold sores usually last around two weeks and are contagious until they crust over and heal.

The Five Stages of a Cold Sore

Cold sores go through distinct stages as they develop and heal:

• Tingling and itching: You may feel these symptoms about 24 hours before the blister appears.
• Blisters: Small, fluid-filled blisters form, typically around the mouth.
• Bursting: The blisters burst and form painful sores.
• Scabbing: The sores dry out, scab over, and may itch or crack.
• Healing: The scab falls off, and the cold sore heals.

Risk Factors for Cold Sores

Certain factors can trigger the reactivation of HSV, leading to cold sores. These include:

• Infection, fever, or cold
• Sun exposure
• Stress
• Menstruation
• Dental work or injury
• Weakened immune system due to conditions like HIV/AIDS, eczema, or chemotherapy

Managing and Treating Cold Sores

There’s no cure for cold sores, but several treatments can ease the symptoms and help manage outbreaks.

Topical Ointments and Creams

Over-the-counter antiviral creams like docosanol (Abreva) or prescription ointments like penciclovir (Denavir) can help reduce the duration of an outbreak, especially if applied at the first sign of a cold sore.

Oral Medications

Prescription antiviral medications like acyclovir, valacyclovir, and famciclovir can also help, particularly for people who have frequent or severe outbreaks. Your doctor may recommend taking these medications regularly to prevent future outbreaks.

Home Remedies

There are also some home remedies that may provide relief, such as:

• Applying ice or a cold washcloth to the sore
• Using aloe vera gel or lemon balm lip balms
• Applying petroleum jelly to ease discomfort

Canker Sores vs. Cold Sores: What's the Difference?

While cold sores and canker sores may seem similar, they are quite different:

Cold sores are caused by the herpes virus, appear around the mouth, and are contagious.

Canker sores are not contagious and appear as ulcers inside the mouth or throat.

Preventing the Spread of Cold Sores

To avoid spreading cold sores:

• Wash your hands frequently
• Avoid close contact with others during an outbreak
• Don’t share food, drinks, or personal items like lip balm

Cold sores can be a persistent issue, but with proper care and management, you can reduce the frequency of outbreaks and prevent spreading the virus to others.

Josie Gibson, English TV personality, opened up about her secret health disorder and that she is turning to a "last resort" surgery for the same. She revealed that this health challenge has left her with extreme pain. This Morning presenter, 40, appeared on the show and spoke to Cat Deeley and Ben Shephard about being diagnosed and having a "lipodema" body. She said, "A couple of years ago somebody actually said on Instagram, 'you have got a typical lipodema body'. I thought, 'what's lipedema?'"

She said she did not even have a clue, but she knew something was not right. But she did not know what lipedema was. She got diagnosed about a year ago and had a surgery. She told her fans that she has been "constantly fighting" her genetics.

What Did Josie Gibson Reveal About The Surgery?

Speaking on ITV’s This Morning, Gibson said surgery was a “last resort” but described herself as happy with the results after spending around £7,000 on liposuction to treat her calves. She explained that the procedure, which combines liposuction with a technique that tightens the skin, had to be carried out in stages.

“The last thing I want to do is put myself through surgery, but it was my last resort,” she said, adding that she had only treated her calves so far. Gibson said the change in her appearance had been significant, telling viewers: “All my life I have wanted to have ankles. I’ve finally got them.”

What Is Lipedema?

Lipoedema is a condition that mainly affects women and causes an abnormal build-up of fat, most commonly in the legs and sometimes the arms. It can make the lower body appear out of proportion and is often associated with pain, tenderness and a feeling of heaviness.

Gibson said she had always felt something “wasn’t right” with her body but was only diagnosed with lipoedema last September. She said specialists told her that diet and exercise would not remove the affected fat. “They said I could train seven days a week and I wouldn’t get rid of lipoedema fat like that,” she said.

Describing the impact of the condition, Gibson said her legs felt increasingly out of place compared with the rest of her body and that symptoms had worsened over time, now also affecting her arms. “I could train, train and train but really, I’m going down the surgery route now,” she added.

Lipoedema specialist Dr Dennis Wolf, who also appeared on the programme, said the condition is not currently treated on the NHS due to the lack of a formal diagnostic test and limited research. He said doctors often rely on symptoms and patient experiences to identify it and believes some people may have a genetic predisposition.

Dr Wolf explained that lipoedema fat is resistant to weight loss, meaning people can exercise and diet without seeing changes in affected areas. While surgery is the most common way to manage the condition, other treatments include compression garments to help reduce discomfort.

Gibson also shared a light-hearted moment from her surgery, admitting the anaesthetic left her flirtatious and apologetic towards her surgeons.

Fewer people are dying of heart disease, however, as per a new report from the American Heart Association (AHA), it is still the leading cause of death in the US. While the report noted a drop in rates of deaths by heart diseases for the first time in five years, the report also noted that it kills more American than any other condition. The report was published early Wednesday in the journal Circulation.

What Did The AHA Report Reveal?

The report found that annual rates of heart disease deaths have in fact decreased by 2.7% between 2022 and 2023. This means it went from 941,652 to 915, 973. However, cardiovascular diseases still killed more people in the US than cancer and accidents combined.

The report found that deaths caused by blockages in the coronary arteries, the blood vessels supplying the heart, fell by 5.9%, dropping from 371,506 to 349,470 over the same period. Coronary artery disease, a major cause of heart attacks, still claims two lives every three minutes. Other vessel-damaging chronic conditions also remain widespread.

The report found that the share of U.S. adults with high blood pressure edged up to 47.3%, while overall obesity rates dipped slightly to 50%. However, obesity is increasing among children and teenagers, rising from 25.4% to 28.1% in those aged 2 to 19.

Prevention remains the most powerful tool to reduce heart disease deaths, experts say. Because heart disease cannot be cured, waiting for symptoms often means focusing only on treatment rather than stopping the problem early. Early prevention, by contrast, has a much bigger impact on saving lives.

The report highlights four key lifestyle habits for heart health: eating a balanced diet, staying physically active, getting enough sleep and avoiding tobacco. It also stresses four important health measures: managing weight, cholesterol, blood sugar and blood pressure.

Together, these eight factors could prevent up to 40% of heart disease deaths and cut the risk of developing serious heart disease symptoms by as much as 74%. These same habits also benefit the brain, helping slow brain ageing and lower the risk of dementia, especially by keeping blood pressure under control.

Heart Health Is Also an Economic Issue

Cutting down cardiovascular disease in the U.S. would not only help people live healthier lives, it could also ease the strain on the economy, experts say. Heart disease carries a massive financial cost, with an estimated $414.7 billion spent each year on direct treatment and indirect losses between 2021 and 2022.

Even though the benefits of healthy habits are well known, getting people to prioritize heart health remains difficult. Only one in four U.S. adults meets national guidelines for both aerobic and muscle-strengthening exercise. Control of chronic conditions is also lacking, with less than half of Americans with type 2 diabetes managing their disease effectively.

Experts stress that regular physical activity, tailored to individual ability, can make a real difference. Simple, consistent movement and timely health checkups can go a long way in protecting both personal health and the wider economy.

Been noticing yellow deposits on your or your loved ones' eyelids? It may be a sign of a future heart attack, experts warn.

Xanthelasma is a harmless, yellow growth that appears on or around the corners of your eyelids next to the nose. These lesions are often painless and can vary in size, sometimes merging to form larger patches.

But while xanthelasma itself is not a disease, its development can signal elevated cholesterol levels and an increased risk of cardiovascular diseases such as coronary artery disease and atherosclerosis, which can lead to a heart attack in the future.

According to Dr Sudhir Kumar, a neurologist associated with Apollo Hospital in Hyderabad, xanthelasma patches can appear even when blood tests show normal cholesterol levels and should prompt 'a proper lipid evaluation, not just a cosmetic procedure'.

In an X post, he noted: "These yellow patches on the eyelids are NOT just cosmetic. They are called xanthelasma and they can be your skin’s clue to hidden heart risk. These are:

1. Often linked to abnormal lipids

2. Can be present even when LDL cholesterol is normal

3. Strongly associated with atherosclerosis & heart disease"

Heart attacks occur when blood flow to the heart is severely reduced or blocked due to a buildup of plaque which is made of fat, cholesterol and other substances in the heart's arteries.

During a heart attack, a lack of blood flow causes the cells and tissue in the heart muscle to die, leading to irreversible damage that can result in serious complications like arrhythmias, heart failure, cardiogenic shock, or cardiac arrest

It is one of the leading causes of death in the country. Four Indians experience a heart attack every minute, with one in four dying of the cause. Experts have also noticed a rising trend of nearly 50 percent of heart attack patients being under the age of 40, with half of all heart attacks in Indian men occurring under 50.

Who Is At The Highest Risk For Xanthelasma?

• Being Overweight.
• A tobacco product habit.
• High cholesterol.
• Diabetes.
• High blood pressure.
• Family history of high cholesterol or xanthelasma are also at the highest risk of developing yellow plaques.

Can Xanthelasma Be A Sign Of Other Diseases?

Additionally, it can also indicate thyroid issues such as hypothyroidism. Xanthelasma and hypothyroidism are linked as both thyroid dysfunction and high cholesterol/lipid levels, often seen with hypothyroidism, can cause the eyelid plaques.

Coronary Artery Disease: The Silent Killer

Coronary artery disease (CAD) is one of the most common illnesses that can cause a heart attack in people. It develops over the years and has no clear signs and symptoms apart from a heart attack.

The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.

Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead to chest pain (angina), shortness of breath and ultimately, heart attacks.

Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis, can increase the risk of developing CAD.

Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.
