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.
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.
The viruses that cause a sore throat are usually similar to a cold in their symptoms and tend to be milder than bacterial infections.
- 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, mainly strep throat, are more severe and require prompt medical attention to prevent complications.
- 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.
Throat irritation is caused by postnasal drip. Allergies create a buildup and drip of mucus down the back of the throat.
- 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.
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.
Viral infections and allergies often respond well to non-invasive treatments:
Let your body rest sufficiently. Humidifying dry air will help keep the throat moist, especially when winter is on its way.
Bacterial infections require antibiotics such as penicillin or amoxicillin. Finish the treatment completely to avoid reoccurrence or resistance.
Prevention is better than cure, and simple lifestyle changes can reduce your risk:
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.

Arthritis is sometimes treated like a normal part of getting older. Yet it can show up in many age groups. It can also limit how freely someone moves. That can affect daily independence and overall comfort.
Some people think arthritis care always means an operation, like joint replacement. In reality, the path to care is wider. What happens next depends on symptoms, which joint is affected, a person’s age, how active they are, and their general health.
Where the disease is in its early stages or is perceived to be mild, treatment will begin in a very low-key manner. This will involve physiotherapy and exercise. Where necessary, losing excess body weight can be beneficial. Minor changes in daily activities will decrease stress. Doctors will prescribe medication depending on the situation. Here, the main objective is to alleviate symptoms and maintain function. It will not be the initial step and will only be considered where appropriate.
In case arthritis is severe, pain and stiffness will persist for a long period of time. Performing simple activities becomes difficult. Even walking will become challenging. Sleep may also be affected. When this happens, it helps to check again. Doctors can use exam findings and imaging to see how much the joint has changed. They can also review whether non-surgical care is working as expected.
Good arthritis care is about choosing the right path for the right person. Timing matters too. It begins with a close look at symptoms and a clear diagnosis. Sometimes it also means getting scans when they are needed. After that, the plan should rely on what the best research shows.
Treatment should be set up with rehab in mind. The aim is to fit the person, not just the label on the chart. One person may do well with physical therapy and simple habit shifts. Another person may need a procedure, mainly when a joint is badly worn.
The main goal is easier daily comfort and better movement. Just as important, it should help someone keep their independence. It is also not only about chasing the newest option.
People should not wait until pain makes normal life hard. When they seek help early, it can be easier to see what is driving the joint pain. It can also help show how far the arthritis has gone. With that in hand, a care plan can be built with more clarity.
When care starts early and matches the person, many can stay active longer. They may also better protect joint function and keep it working well for more time.

As pollution levels rise in October, doctors warn that exposure to particulate matter can affect lung and heart health, aggravate existing respiratory conditions, and cause symptoms even in otherwise healthy individuals, particularly as winter approaches.
PM2.5 and PM10 can irritate the respiratory tract, while fine particles such as PM2.5 can penetrate deep into the lungs, with some entering the bloodstream.
Delhi woke up to poor air quality on Thursday, with the Commission for Air Quality Management’s (CAQM) AQI dashboard recording an Air Quality Index (AQI) of 226 across Delhi-NCR at 7 am.
As per the CAQM’s dashboard, some areas of the national capital recorded very poor air quality, with an average AQI of 307.
The Commission for Air Quality Management (CAQM) on Wednesday imposed Stage I of the Graded Response Action Plan (GRAP) across Delhi-NCR after the capital's air quality slipped into the 'poor' category.
According to the Air Quality Early Warning System, Delhi's air quality is likely to remain in the 'poor' category until October 23. The forecast for the following six days also indicates that pollution levels are likely to remain in the same category.

Dr. Amit Kumar Mandal, Senior Director - Pulmonology, Paras Health Panchkula, told HealthandMe that air pollution can cause inflammation in the airways and worsen asthma, chronic obstructive pulmonary disease (COPD) and other respiratory conditions. It can also increase the risk of cardiovascular complications.
The effects may not always be immediately noticeable. People may experience persistent coughing, throat irritation, wheezing or breathlessness. Repeated exposure over time can contribute to more serious health problems, even in people without pre-existing conditions.
Dr. A.S. Sandhya, Consultant, Pulmonary & Sleep Medicine, Kailash Hospital & Neuro Institute, told HealthandMe that October can mark the beginning of a prolonged period of poor air quality in Delhi-NCR.
When pollution combines with changing weather conditions, people with asthma, bronchitis and COPD may experience more frequent symptoms. However, healthy individuals can also develop eye irritation, coughing, throat discomfort and reduced exercise tolerance after exposure to polluted air.

Doctors recommend monitoring daily AQI levels and limiting exposure when air quality is poor.
Dr. Mandal advises reducing prolonged outdoor activity and avoiding exercise near busy roads during high-pollution periods. Children, older adults, pregnant women and people with respiratory or heart conditions should take extra precautions.
Dr. Sandhya recommends limiting strenuous outdoor exercise when pollution levels are high and using a well-fitted N95 mask when outdoor exposure cannot be avoided.
Indoor air quality also matters, particularly for children and older adults who spend extended periods at home. Air purifiers with suitable filtration may help reduce indoor particulate matter, although they do not eliminate all pollutants.
People should not ignore persistent coughing, wheezing or unusual breathlessness. Those experiencing persistent breathing difficulties, chest discomfort or worsening respiratory symptoms should consult a doctor.
People with existing medical conditions should follow their treatment plans and seek medical advice if their symptoms worsen.
Taking preventive measures now, rather than waiting for pollution to peak in winter, can help reduce exposure and the risk of avoidable health complications in the months ahead.

Climate change is not just raising temperatures and intensifying extreme weather. It may also affect digestive health by disrupting food production, threatening water security and changing the spread of gastrointestinal infections, according to two leading gastroenterology experts from the World Gastroenterology Organization (WGO).
Climate change can contribute to heat-related illnesses and influence the geographic spread of infectious diseases, especially in countries like India.
A February 2025 review in The Lancet Planetary Health outlines how the combined effects of climate change could affect the human gut microbiome, including through food insecurity, malnutrition and exposure to disease-causing pathogens. These challenges could alter the composition of gut microbial communities worldwide.
Research suggests that heat stress may alter gut microbes, digestion and immune function. It may also increase intestinal permeability, potentially allowing toxins and pathogens to enter the bloodstream.
Climate-related drought can disrupt food production and reduce access to nutritious food, potentially affecting the gut microbiome. Environmental changes may also influence food- and waterborne pathogens, increasing infection risks where access to safe water and sanitation is limited.
Speaking to HealthandMe, Professor Geoffrey Metz, professor of medicine at the University of Melbourne, said climate change was becoming an increasing concern for gastrointestinal health.
“Certainly, with global warming, we're seeing a lot more infectious diseases in the gastrointestinal tract,” Metz said.

Climate change can affect digestive health through several interconnected pathways, including water availability, food production and infectious diseases.
Metz said the consequences of global warming extend beyond rising temperatures.
“The other thing, of course, with global warming—and this is a major interest of the World Gastroenterology Organisation—is that it's not just making us hot, but it's also creating more drought, which interacts with food production. So there's less food available, impacting our nutrition.”
Drought can disrupt food production and reduce food availability, raising concerns about nutrition. Changes in water availability can also make safe food preparation and hygiene more difficult.
However, the extent to which these environmental changes contribute to specific gastrointestinal diseases requires further investigation.
Professor Carolina Olano, professor of gastroenterology in Montevideo, Uruguay, and president of the WGO, highlighted the role of environmental factors in digestive diseases.
“Well, I think it's a combination of many factors. You know that there are some things related to genetics, and we have genetic predispositions to some diseases. But there are also environmental factors related to different diseases, and climate change has an impact too. We are working very hard at the World Gastroenterology Organisation to understand how climate change is affecting different diseases.”
Olano also emphasised the importance of safe drinking water and food hygiene in preventing infections.
“It's also important to have a varied diet and to drink safe, clean water, making sure that the water we drink is safe. Food hygiene is also extremely important.”
She told HealthandMe that handwashing was another simple preventive measure.
“We learned from the COVID pandemic that handwashing before eating is extremely important. These are things we can do every day without spending anything, and they can help prevent many important diseases, especially those related to infections.”

The effects of climate change may extend beyond the digestive system, affecting multiple aspects of health.
“Global warming is not just affecting how we feel; it's also having an effect on heart disease, lung disease, gastrointestinal disease, obstetrics and gynaecology,” said Metz, who is also the former president of the WGO.
Olano also pointed to population movements as a factor to consider when assessing environmental and health risks.
“As you know, it's not only about weather and climate change. It's also about how populations move from one country to another and what the impact of these movements is when people move from one region to another.”
“Because, as you know, it's not only about weather and climate change. It's also how populations move from one country to another and what the impact of these movements is when people move from one region to another.”
Understanding these connections is important as researchers investigate how climate-related environmental changes may influence disease patterns across regions.
While individuals cannot control climate-related changes, Olano highlighted everyday measures that can help prevent infections and support digestive health:
She also stressed the importance of seeking medical advice about hepatitis prevention, vaccination and testing where appropriate, as well as colorectal cancer screening.
Climate change presents a broader public health challenge, but safe water, food hygiene and infection prevention remain important measures for reducing avoidable digestive health risks.
