One of the commonest causes of illness, a sore throat often clears up on its own, but knowing what's causing it is important to treat it properly. Viral, bacterial, or caused by allergic elements - these kinds of sore throats have different characteristics that need different responses.

Sore throats have several origins, including infection and environmental factors. Some common causes include:

Viral infections: Viruses cause 90% of sore throat cases. Sore throats may result due to flu or common cold as well as those from chickenpox and measles that can all cause irritation.

Bacterial Infections: Streptococcus bacteria, the most common cause of strep throat, is the most common bacterial source. Strep throat is contagious and can lead to complications if untreated.

Allergies: Pollen, pet dander, and mold can trigger throat irritation, often accompanied by postnasal drip, sneezing, and watery eyes.

Environmental Factors: Dry air, pollution, and smoke can dry out or irritate the throat, creating a scratchy sensation.

Other Causes: GERD, vocal strain, even tumors may be responsible for chronic sore throats.

How to Distinguish Between Viral, Bacterial, and Allergic Sore Throats

Determining your cause of sore throat requires analysis of symptoms that accompany it, how long the sore throat lasts, and how bad the sore throat is.

Viral Sore Throats

The viruses that cause a sore throat are usually similar to a cold in their symptoms and tend to be milder than bacterial infections.

Symptoms of Viral Sore Throat

- Red, swollen throat without white patches

- Persistent cough

- Runny nose and nasal congestion

- Fever, usually mild

Duration: Viral infections last for 7–10 days without antibiotics.

Treatment: Home remedies, such as warm fluids, saltwater gargling, and over-the-counter pain relievers can help alleviate it.

Bacterial Sore Throats

Bacterial sore throats, mainly strep throat, are more severe and require prompt medical attention to prevent complications.

Symptoms of Bacterial Sore Throat

- Red and swollen tonsils with white patches or streaks of pus

- High fever

- Absence of a cough

- Nausea, vomiting, or stomach pain (especially in children)

- Small red spots on the roof of the mouth

Diagnosis: Rapid strep tests or throat cultures confirm the presence of bacteria.

Treatment: Antibiotics are necessary to eliminate the infection. Without treatment, complications like rheumatic fever or abscesses can develop.

Sore Throats Caused by Allergies

Throat irritation is caused by postnasal drip. Allergies create a buildup and drip of mucus down the back of the throat.

Allergic Sore Throat Symptoms

- Irritation of the throat and ears

- Runny eyes, sneezing, and nasal congestion

- These symptoms are usually relieved by antihistamines or removal from the source of the allergen

Duration: Allergic sore throats are sustained for as long as the allergens are exposed.

When to Seek Medical Care?

A sore throat should be taken to a doctor if:

- The condition lasts more than a week.

- There is shortness of breath or swallowing becomes painful.

- Swelling is too pronounced or the pain in the throat is extreme.

- High fever, rash, or joint pain occur along with the sore throat.

- A child shows signs of dehydration or refuses fluids due to throat pain.

Early diagnosis can prevent complications and speed recovery.

Effective Treatment for Sore Throats

Home Remedies for Viral and Allergy-Related Sore Throats

Viral infections and allergies often respond well to non-invasive treatments:

• Drink warm teas, broths, or water to soothe the throat.
• Gargling with warm, salty water can reduce inflammation.
• These help soothe an irritated throat and can alleviate coughing.

Let your body rest sufficiently. Humidifying dry air will help keep the throat moist, especially when winter is on its way.

Why Not All Sore Throats Require Antibiotics?

Bacterial infections require antibiotics such as penicillin or amoxicillin. Finish the treatment completely to avoid reoccurrence or resistance.

How to Keep Sore Throats at Bay When Winter Is Near

Prevention is better than cure, and simple lifestyle changes can reduce your risk:

• Wash your hands frequently to avoid infections.
• Avoid close contact with sick individuals.
• Use air purifiers to minimize exposure to irritants.
• Stay hydrated and maintain a balanced diet to boost immunity.

Understanding the cause of your sore throat—whether viral, bacterial, or allergic—is key to effective treatment and recovery. While many sore throats resolve on their own, seeking timely medical advice for persistent or severe symptoms can prevent complications. Prioritize self-care, and don’t hesitate to consult a doctor when needed. Remember, your throat’s health is a vital part of your overall well-being.

Dianna Cowern, the science communicator with more than two million YouTube subscribers, was at the peak of her career in 2022. Featuring millions of views, her YouTube channel ‘Physics Girl’, featured her travelling across the world filming science videos. She had also recently married her longtime partner, Kyle Kitzmiller.

Then, after contracting COVID-19 during her honeymoon in Scotland, her life took a turn in ways she could not have anticipated.

What initially started off as a mild infection was followed by a sharp decline in her physical and mental health. A hike she had planned with her husband became an impossible task for her. After that rest no longer seemed to help her recover.

Cowern's experience highlights the disabling effects of Long COVID, a condition that researchers are still trying to understand.

She recalled the time when her symptoms escalated, “Brain fog like I'd never experienced before. I couldn't walk. I couldn't think. I had nausea and headaches,” she said. “And I never recovered from that crash.”

According to KPBS, Cowern's initial COVID-19 symptoms included a sore throat, cough and stuffy nose. After they subsided, she and Kitzmiller began a multiday hike they had planned for months. By the third day, she was struggling to recover even after resting and had to take a cab to the next location while her husband continued on foot.

The couple cut their honeymoon short and returned to San Diego. Her health continued to decline. She first lost the ability to run and hike, then struggled to work and walk. Eventually, she became unable to speak, read or use her phone.

Sensitivity to light and sound left her spending her days in a dark room, wearing dark glasses and noise-cancelling headphones to limit stimulation. Kitzmiller became her full-time caregiver.

He also recalled episodes in which her heart rate dropped into the 30s. He used a pulse monitor with an alarm and slept waiting for it to sound. “Every day I didn't know if she was just gonna die,” he said.

The couple sought medical help, but tests failed to provide clear answers. Kitzmiller described the response they had received from doctors. He said they said, “There's not a real disease here.”

Long COVID Is Part Of Post-Acute Infection Syndromes

Long COVID refers to symptoms that occur after a SARS-CoV-2 infection and cannot be explained by another diagnosis. Symptoms vary widely and may include fatigue, cognitive difficulties, breathlessness, sleep disturbances and problems with everyday activities.

Some people improve over time, while others experience prolonged illness that affects their ability to lead routine lives.

Long COVID is also part of a bigger group of conditions known as post-acute infection syndromes, in which people continue to experience symptoms after an infection has gone.

Researchers are examining possible explanations behind Long COVID, including prolonged immune dysfunction and other changes triggered by infection.

Treatments Improved Symptoms But Road To Recovery Was Far

With few established treatment alternatives available, Cowern explored options suggested by researchers, although they were not approved for Long COVID. She reported a significant improvement after trying some of them.

“I was able to start looking at my phone again and reading and listening to music, which was amazing,” she said. “And then everything improved.”

After three years, she eventually returned to making science videos. But her return has not meant a full recovery. Cowern says that she is functioning at around 30% to 40% of her previous capacity.

She and Kitzmiller are now using their platform to raise awareness about chronic illness. Kitzmiller has also joined an advisory committee for clinical trials investigating a treatment that helped her.

“There’s still a lot to learn,” Cowern said. “There's so little that's understood about this disease, but I will say that everyone that has it is desperate to live again.”

Air pollution, chemicals that interfere with hormonal health and stress due to climate may be contributing to South Asia’s growing burden of diabetes and heart disease. The Lancet study has highlighted the importance of considering other factors than diet and physical inactivity when addressing metabolic health.

A paper published in The Lancet Regional Health – Southeast Asia argues that the environmental conditions people face throughout their lives could play a key role in worsening cardiometabolic health.

The authors specifically point to a combination of exposures, from fine particulate matter in polluted air to chemicals in consumer products, that could influence how body regulates blood sugar, stores fat and maintains healthy blood vessels.

The paper, titled South Asia’s cardiometabolic burden: exposomal determinants of a health transition, was authored by Misra and Yashendra Sethi of the Department of Medicine at Subharti Medical College, Swami Vivekanand Subharti University, Meerut.

Effects Of Environmental Exposures On Metabolic Health

The authors use the term “exposome” to denote the range of environmental factors a person sees over their lifetime living in a particular city. These include air pollution, chemical contaminants, dietary patterns, sleep pattern and stress.

Fine particulate matter, or PM2.5, is the primary concern, according to the authors. These tiny airborne particles can seep deep into the lungs and cause inflammation that could worsen cardiovascular and respiratory illness.

The paper also highlights how prolonged exposure may contribute to metabolic dysfunction, including oxidative stress, insulin resistance and damage to the lining of blood vessels.

Chemical exposures are another area of concern. Bisphenols, phthalates and per- and polyfluoroalkyl substances (PFAS), found in various industrial and consumer applications, can interfere with hormone health. Depending on the level of exposure, these chemicals may have an effect on insulin sensitivity, appetite and fat cells in the body.

Other lifestyle will only fuel these risks. Irregular sleep, shift work and disrupted body clocks can interfere with metabolic health, while unhealthy diets featuring ultra-processed foods and stress may contribute to inflammation and other reasons that lead to chronic diseases.

The authors say that these overlapping exposures could help explain why conditions like type 2 diabetes, steatotic liver disease and cardiovascular disease are becoming alarming public health concerns in South Asia. However, the contribution of individual exposures and their combined effects requires further investigation.

South Asians Face Greater Risks Of Chronic Diseases

South Asians can develop type 2 diabetes and cardiovascular disease at younger ages and at lower body mass index levels than many Western populations. The paper places the region’s rapid economic and social transformation behind this vulnerability.

It means that generations that experienced undernutrition for centuries now live in environments influenced by urbanisation, better transport, changing diets and greater exposure to pollution. Biological tendencies towards energy storage may interact with these newer conditions, increasing metabolic risk.

Across the Asia-Pacific region, the burden of cardiometabolic disease, measured in life years after adjusting disability, rose between 1.7-fold and 3.7-fold from 1990 to 2023.

Approach For Prevention

The authors argue that advice on eating well, exercising and sleeping adequately remains important, but they cannot help when people have limited control over the air they breathe or the environmental quality.

The paper recommends monitoring environmental exposures, intervening early in life, strengthening food policies, and conducting long-term research to understand how exposures influence cardiometabolic outcomes.

The boom in GLP-1 weight loss drugs is not only affecting the obesity market but also reshaping the beauty industry. Changes in consumer behaviour among those who use GLP-1 drugs is evident as people may see differences in their appearance after drastic weight loss. This phenomenon has prompted global beauty companies to explore products for people experiencing changes in their appearance after losing weight.

French cosmetics giant L’Oréal is among the companies exploring this emerging market segment. Its CEO, Nicolas Hieronimus, said the increasing use of these medications was affecting beauty and skincare consumption, compelling the company to explore products that address concerns like sagging skin after extreme weight loss.

“The rise in their (GLP-1 drugs) use was having an impact on beauty consumption and skin care consumption in particular,” Hieronimus said during an investor call on October 22, after the company's third-quarter results came out.

The development mirrors an important shift in the beauty industry as weight loss medications like Ozempic, Wegovy and Zepbound become more widely used for weight management.

Amid the growing market for these drugs, companies are now seeing increased demand for treatments that help changes in facial volume, skin firmness and elasticity after weight loss.

However, the science behind ‘Ozempic face’ is far more complicated than the name suggests. Experts say these changes are generally associated with losing facial fat during weight loss, especially when it happens rapidly.

What is ‘Ozempic Face’?

‘Ozempic face’ is an informal term for facial changes that occur after rapid and substantial weight loss. It is marked by hollowing around the cheeks and temples and more noticeable wrinkles or sagging skin.

GLP-1 medicines, including semaglutide and tirzepatide, act on appetite regulation, helping people feel fuller for a long time and reducing their calorie intake. As a result, some people lose a substantial amount of weight over a short period.

Beauty Companies Respond to GLP-1 Boom

Apart from L’Oréal, Swiss skincare company Galderma and Brazilian cosmetics group Natura are also seeing similar demands from consumers experiencing changes in their facial skin after medicated weight loss.

L’Oréal has said that it is testing products on people using GLP-1 medications. Its SkinCeuticals range also has products intended to address concerns such as skin sagging, according to Hieronimus.

“We have products in SkinCeuticals that are made to work alongside GLP-1 drugs and address their side effects, such as skin sagging and other related issues. It is very integrated,” he said.

Galderma, in which L’Oréal holds a 20% stake, has assessed some of its existing aesthetic treatments for changes due to GLP-1 use. Its portfolio includes Sculptra, an injectable that stimulates collagen, and Restylane, a range of hyaluronic acid-based dermal fillers.

Anne-Cecile Chevrier, Galderma's global head of injectable aesthetics, described the concerns that experts are seeing among consumers. “Sagginess is a concern, loss of firmness is a concern, some hollowness can be of concern and dullness can be a concern,” she said.

Can Skincare Products Reverse ‘Ozempic Face’?

The expansion of this market does not necessarily mean that skincare products can reverse facial changes due to rapid weight loss.

The skin has several layers, and topical products act on the skin's surface. Facial fat loss happens when fat accumulated beneath the skin melts off. Skincare products cannot simply replace this process.

Dr Graeme Glass, a plastic and craniofacial surgeon and aesthetic director at British beauty brand LYMA, explained the limitations of topical treatments. “They can't reposition the deep fat pads of the face. There is a limit to what these things can do,” he said.

Moisturisers and other products may help improve hydration, texture and the appearance of fine lines. But these benefits should not be confused with correcting sagging skin.

Treatments like fillers and collagen injectables may address these concerns directly, but they involve different risks, costs and clinical considerations.

Avani Sinha, MD, and FACE endocrinologist and program director of the Northwell Health Division of Endocrinology, Diabetes and Metabolism fellowship told Women's Health Magazine that it is important to take care of nutrition and muscle-building to "fill up spaces where you are losing that skin laxity".

“We are what we eat, we are what we do,” she said, stating that protein intake is especially important on a GLP-1. She suggested aiming 0.8 to 1.8 grams per kilogram of body weight.

Sinha also recommended staying hydrated along with strength training to build muscle. “You build up that muscle, you're going to fill up those spaces where you're losing that skin laxity,” she said.
