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.

Amanda Peet, the Hollywood actress known for roles in Something’s Gotta Give, The Whole Nine Yards, and Jack & Jill, recently opened up about her breast cancer diagnosis and how informing her kids about her health became the toughest part for her.

In a New Yorker essay published March 21, the 54-year-old actress announced how a routine scan in August 2025 showed an unusual ultrasound result. Later, a biopsy detected a tumor that “appeared” small.

The Dirty John star found to be in stage 1 of lobular cancer that is “hormone-receptor-positive” and “HER2-negative,” making her “happier than the pre-diagnosis” stage.

It is because Hormone-receptor-positive and HER2-negative cancer is less aggressive and often easier to treat than more aggressive forms of breast cancer.

However, informing her children, Frances, 19, Molly, 15, and Henry, 11, about the cancer was the toughest part for her, and she had to be in the right mindset before sharing the news with them.

“They've been great,” Peet told E! News.

“I definitely had to get myself together before including them. The hard part was realizing that nothing is certain and there was going to be no perfect time to tell them,” she added.

Peet stated that between her diagnosis, she had also been navigating a series of family health crises — with both of her parents' final months in hospice care.

The Your Friends & Neighbors actress, in her essay, also noted that she would “only need a lumpectomy and radiation,” not a double mastectomy.

What is Lobular Cancer?

Invasive Lobular Carcinoma (ILC) the second most common form of breast cancer, representing 5 to 15 percent of breast cancer cases.

Rather than a distinct lump, it can appear as a thickening or "fullness" rather than a tumor.

It is often difficult to detect on mammograms, thus MRI or ultrasound are more effective for detection

It is usually hormone receptor-positive.

What Is Hormone receptor-positive (HR+) and HER2-negative (HER2−) Breast Cancer

HR+ and HER2− breast cancer is the most common subtype and is seen among 60–75 per cent of cases.

It is not two different cancers, but rather specific, defining characteristics of the same cancer type (breast cancer). It grows:

• due to hormones estrogen/progesterone,
• lacks excess HER2 protein,
• it can occur in either or both breasts
• has a better prognosis
• slower growth rate
• often treated with hormone therapy and sometimes chemotherapy.

Why Early Diagnosis Matters for Breast Cancer

According to the Centers for Disease Control and Prevention (CDC), breast cancer screening is a proactive checkup used to find cancer before any physical signs or symptoms appear. While screening doesn’t prevent cancer, its goal is early detection, making the disease much easier to treat.

Since every person’s body and history are different, you and your doctor should engage in informed and shared decision-making. This means discussing the pros and cons to decide together if, and when, screening is right for you.

The US Preventive Services Task Force (a group of national medical experts) provides guidelines based on the latest research:

Average Risk

Women aged 40 to 74 should generally get a mammogram every two years.

High Risk

If you have a family history or other risk factors, your doctor may recommend a different schedule or additional tests.

GLP-1 receptor agonists are a modern class of medicines that have changed the treatment of type 2 diabetes and obesity. In simple terms, they help the body respond to food more smartly. After eating, the intestine naturally sends signals that help regulate sugar and appetite levels.

GLP-1 RA medicines imitate this signal. As a result, blood sugar rises less after meals, appetite becomes more controlled, and many people feel full with smaller amounts of food. This is why these medicines are used not only for diabetes, but also for weight reduction in selected people.

GLP-1 Drugs: Not A Miracle Injection

These medicines are important because their benefits can go beyond sugar control alone. Studies and current diabetes guidelines show that some GLP-1 RAs can reduce body weight, improve long-term sugar levels, and lower the risk of major heart-related problems in people who have type 2 diabetes and high cardiovascular risk.

Recent guidance also supports their use in some people with chronic kidney disease when cardiovascular risk reduction is an important goal. This does not mean every drug in the group is identical, but it means the class has become medically important for more than just lowering sugar.

For the general public, one important point is that these are not “miracle injections.”

They work best when combined with better food choices, regular walking or exercise, good sleep, and medical follow-up. They are usually started slowly because the commonest side effects are stomach-related, such as nausea, vomiting, constipation, loose motions, or a feeling of fullness.

Not everyone is suitable for them, and the decision depends on a person’s diabetes status, weight, heart or kidney disease, other medicines, and cost. Used properly, GLP-1 RAs are powerful tools that can improve health, but they should always be taken under medical supervision.

GLP-1 Drugs: Urgent Need to Curb Misuse

So Indian Medical Association (IMA) is planning to seek a mandate restricting prescriptions of GLP-1 drugs to certified endocrinologists/diabetologists or MD general medicine practitioners to curb indiscriminate use and safeguard patient safety as access expands, many media report in August last year about rampant misuse of GLP1 weight loss drugs by cosmetologists, physiotherapists, dermatologists, general MBBS clinicians, and even ayurveda, and other non-modern medicine practitioners.

Many MBBS, physiotherapists, and non-modern medicine practitioners are prescribing GLP1 drugs to people who neither have diabetes nor any comorbidity or acute obesity, but purely for cosmetic reasons to lose some weight that can be otherwise easily done with some lifestyle changes like exercise and diet.

It is a duty of the government to take care of it because there is a lot of misuse and misprescription that needs to be curbed immediately, because these medicines also have side effects.

We will write to the government to take necessary action to stop the misuse of the drug. We will discuss it in our meeting in the first week of April 2026.

One in four or 25 percent of adults with type-2 diabetes in India also suffer from liver fibrosis, according to an alarming study published in The Lancet Regional Health Southeast Asia journal today.

With data from more than 9,000 patients across the country, it is the largest ever real-world survey of liver fibrosis in type 2 diabetes from any low- or middle-income country.

While fatty liver disease has been touted as the most common liver condition among diabetes patients, the new study established liver fibrosis as the real danger among people with high blood sugar.

“Type 2 diabetes is closely linked to fatty liver disease (also known as MASLD). But how common is liver Fibrosis — the real danger — in Indian diabetics? Our answer: 1 in 4 has clinically significant liver fibrosis. One in 20 already has probable cirrhosis. Most had no symptoms. We propose liver fibrosis as the ‘4th major complication’ of diabetes,” said Ashish Kumar, from Ganga Ram Postgraduate Institute of Medical Education and Research (GRIPMER), from Sir Ganga Ram Hospital, in a post on social media platform X.

What Did The Study Find?

Fatty liver is typically the first and reversible stage of liver disease, where excess fat builds up in liver cells. Left untreated, it progresses to liver fibrosis, which is the excessive accumulation of scar tissue (collagen) in the liver resulting from chronic inflammation. The condition then progresses to the third and late stage, irreversible scarring (fibrosis) of the liver. The final stage is liver cancer.

The DiaFib-Liver Study included a total of 9,202 adults with type-2 diabetes patients who underwent FibroScan (VCTE) to assess liver fibrosis in routine diabetes care.

Of these:

• 26 percent had clinically significant fibrosis,
• 14 percent had advanced fibrosis,
• 5 percent had probable cirrhosis
• 65 percent had fatty liver disease.

• obesity
• dyslipidaemia
• kidney problems
• diabetes duration ≥10 years.

Fibrosis: The Screening Target

The study suggested the urgent need to integrate fibrosis screening into national diabetes programs.

“One in four adults with type 2 diabetes in India has clinically significant liver fibrosis and one in twenty already has probable cirrhosis, establishing advanced liver disease as a 'fourth major complication' of diabetes,” said the researchers.

“The DiaFibLiver Study calls for: Fibrosis — not steatosis — as the screening target. FibroScan integration into routine diabetes care. Moving beyond ultrasound-based referral,” Jha said.

“We hope this data from India adds to the global conversation on diabetes and liver disease,” he added.

The findings highlight the urgent need to:

• move beyond steatosis
• systematically integrate fibrosis assessment into routine diabetes care,
• deploy non-invasive tools such as vibration-controlled transient elastography (VCTE) in community practice
• define screening strategies,
• evaluate therapeutic interventions.

Everyday Habits That Harm the Liver

Certain lifestyle choices can accelerate liver damage, such as:

Overeating processed or fried foods

High sugar intake (soft drinks, sweets, desserts)

Physical inactivity or prolonged sitting

Ignoring health issues like diabetes or hypertension

Crash dieting or taking unprescribed supplements.

How To Improve Liver Health?

Early screening and detection are key to prevent irreversible stages. Yet liver disease can be prevented with lifestyle changes such as:

• Eating a balanced diet with vegetables, fruits, whole grains, and lean protein
• Engaging in at least 30 minutes of exercise daily
• Staying hydrated to help the liver flush out toxins
• Avoiding alcohol and smoking
• Avoiding self-medication and unnecessary pills
• Getting routine health screenings.
