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.

Fatty liver disease has traditionally been associated with obesity and alcohol consumption. However, in clinical practice, we are increasingly seeing fatty liver in individuals who may not appear overweight and who do not consume alcohol. This changing pattern reflects a larger problem: the close relationship between liver health, metabolic health, and lifestyle.
Non-alcoholic fatty liver disease (NAFLD), now increasingly termed metabolic dysfunction-associated steatotic liver disease (MASLD), occurs when excess fat accumulates in the liver in association with metabolic risk factors. A systematic review and meta-analysis of Indian studies estimated the pooled prevalence of NAFLD among adults at 38.6%, meaning that roughly one in three adults may be affected. The prevalence was approximately 28.1% in average-risk populations and increased to 52.8% among individuals with higher metabolic risk.
What is particularly important for Indians is that fatty liver cannot be identified simply by looking at body weight. South Asian populations can develop visceral or abdominal fat and metabolic abnormalities even at relatively lower body mass indices. A South Asian meta-analysis found that NAFLD affected approximately 26.9% of adults in the general population, while prevalence rose to 54.1% among people with metabolic diseases. Importantly, around 43.4% of people with NAFLD in the analysis were not obese.
Diabetes, hypertension, dyslipidaemia, central obesity and metabolic syndrome are therefore important warning signs. In my practice, I often emphasise that a normal-looking body does not necessarily mean a metabolically healthy body. Waist circumference, blood sugar, lipid profile, liver enzymes, and, when indicated, liver imaging provide a much more meaningful risk assessment.
The other misconception is that fatty liver is harmless. Simple steatosis may remain stable in many individuals, but some patients develop inflammation and progressive fibrosis, eventually leading to cirrhosis and liver cancer. A systematic review of hepatocellular carcinoma in India also found that the proportion of cases associated with NAFLD has been increasing, although viral hepatitis remains an important cause. ([PubMed][3])
There is also a broader gastroenterological concern. Digestive and liver health are closely connected with dietary patterns, physical activity, and metabolic health. Excessive intake of refined carbohydrates, sugary beverages, ultra-processed foods, and excessive calories, combined with inadequate physical activity, can contribute to metabolic dysfunction.
The good news is that lifestyle modification can make a substantial difference in fatty liver. Weight reduction, regular physical activity, improved dietary quality, adequate sleep, and better control of diabetes and cholesterol can help reduce liver fat and metabolic risk. Importantly, management should be individualised rather than based on crash diets or unregulated supplements.
Fatty liver should therefore be viewed not merely as an incidental finding on an ultrasound report, but as a metabolic warning signal. Early identification allows us to intervene before irreversible liver damage develops. For patients, the message is simple: taking care of the liver also means taking care of the heart, metabolism, and overall digestive health.
The statistics cited above are based on published systematic reviews/meta-analyses and IARC/WHO data; prevalence estimates vary depending on the population and diagnostic method.

Endometriosis is a chronic disease affecting about 1 in 10 women worldwide. Diagnosis and treatment remain challenging, particularly for women with severe pain and other complications.
Now, US researchers have developed a targeted nanotherapy that showed promising results against endometriosis in early testing.
Scientists at Washington State University found that the treatment reduced endometriosis lesions, symptoms and pain sensitivity after a single dose in mice.
The findings were published in Advanced Healthcare Materials. Researchers hope to eventually test the treatment in humans.

The drug, niclosamide, was previously used to treat intestinal tapeworm infections in humans and is still used in animals.
Earlier research found that niclosamide could reduce endometriosis lesions and inflammation. However, it is not suitable for long-term use, limiting its potential as a treatment for a chronic condition.
To overcome this, researchers developed a nanotherapy that delivers niclosamide directly to cells associated with endometriosis.
“We found the disease-specific immune cell, and then we had a drug, but we couldn’t target the cell with the drug alone,” said Kanako Hayashi, professor at WSU’s School of Molecular Biosciences.
“So we used this nanocarrier that delivers the drug specifically to the disease site,” Hayashi said.
The team used a nanosized molecule called a dendrimer to bind with niclosamide and deliver it in a more soluble form.
In mice, a single injection reduced the size and number of lesions and lowered pain sensitivity.
“Although we still need to clear multiple phases, this study is telling us the efficacy is strong, and this nanocarrier is stable, so far, for two weeks—and we think we can go longer,” Hayashi said.
If the treatment remains stable for longer periods, researchers believe it could potentially be given less frequently. Hayashi said a monthly injection could be possible in the future, but this would depend on further testing.

Not yet. The treatment has only been tested in mice and must undergo further safety and efficacy testing before human trials.
Researchers also do not yet know whether it would ultimately be given as an injection or IV infusion.
Endometriosis affects an estimated 190 million women worldwide. It occurs when tissue similar to the lining of the uterus grows outside the uterus.
It can cause severe pelvic pain, painful periods, pain during sex and infertility. Symptoms are sometimes dismissed as a “bad period,” contributing to delays in diagnosis.
There is currently no cure, although treatments can help manage symptoms.
Treatment depends on symptoms, disease severity and fertility goals.
Hormonal medicines can help control pain and disease activity but may cause side effects and can affect fertility while being used.
Painkillers, including non-steroidal anti-inflammatory drugs, may help manage discomfort.
Laparoscopic surgery can remove lesions and endometriotic cysts and may help restore pelvic anatomy. It can also improve fertility in some women, although the disease can recur.
Lifestyle measures such as regular exercise, stress management and dietary changes may also support symptom management.

Lung development of the fetus depends on the physical and genetic health of the parents.
At birth, breathing begins with air from the environment, containing oxygen and other gases, and is influenced by known and unknown forces of nature. The air then passes through well-developed nostrils, which regulate the air temperature and prevent foreign bodies from entering the body and help protect against diseases.
Breath travels through the nasal passages, sinuses, pharynx (throat), larynx (voice box), trachea (breathing tubes), bronchi, small airways, air sacs, interstitial membrane, into thin-walled blood vessels that transport oxygen and collect gases and other substances to be expelled from the body.
The diaphragm, the muscle that separates the lungs from the abdomen, is the most powerful breathing apparatus.
The lungs in the early stages of life undergo dramatic changes from newborn→ infancy→ childhood→ puberty→ teenage→ adults→ middle age→ seniors. Factors influencing lung health risks keep changing with age, depending on genetics, environment & external factors.
The lungs and airways perform non-respiratory functions of protecting the body against harmful insults, both from within and external threats, and it also protects against insults received from other organs of the body. The lungs have a powerful defense mechanism protecting the body and also have hormonal, physical, and immunological defense mechanisms.
