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.

Organ transplantation can offer patients with end-stage organ failure a new opportunity for a longer, healthier, and more independent life. However, transplantation is not the end of treatment—it marks the beginning of a lifelong commitment to maintaining the health and function of the transplanted organ.
Successful long-term outcomes depend on close collaboration between the organ recipient, living donor, transplant team, and family. Regular medical follow-up, adherence to prescribed medications, a healthy lifestyle, and early recognition of warning signs are essential for both recipients and living donors.
For most solid-organ transplant recipients, lifelong immunosuppressive therapy is required to prevent the immune system from attacking the transplanted organ.
Medications such as tacrolimus, cyclosporine, mycophenolate, corticosteroids, and other immunosuppressive agents may be prescribed depending on the type of transplant and the individual patient's condition.
Recipients should:
• Take medications exactly as prescribed and at the recommended times.
• Never stop or reduce immunosuppressive medication without consulting the transplant team.
• Avoid missing doses.
• Inform their transplant physician before starting any new medication.
Even seemingly minor changes in medication can affect drug levels and may increase the risk of acute or chronic rejection.

Regular follow-up with the transplant team is an essential component of lifelong transplant care.
Depending on the transplanted organ and individual circumstances, monitoring may include:
• Kidney and liver function tests
• Complete blood counts
• Immunosuppressive drug levels
• Blood pressure and blood glucose monitoring
• Urine examination in kidney transplant recipients
• Imaging or other investigations when clinically indicated
These evaluations help detect rejection, infection, medication toxicity, or deterioration in graft function at an early stage, sometimes before symptoms become apparent.

Transplant recipients should promptly contact their transplant team if they develop symptoms such as:
• Unexplained or persistent fever
• Chills or significant weakness
• Reduced urine output, particularly after kidney transplantation
• Swelling or sudden weight gain
• Breathlessness or persistent cough
• Persistent pain over the transplant site
• Persistent vomiting or diarrhoea
• Unexplained changes in blood pressure or blood sugar
Because immunosuppressive medications reduce the body's immune response, infections may develop more easily and may sometimes present with subtle symptoms. Early medical assessment is therefore important.
Transplant recipients are more susceptible to infections, particularly during periods of intensive immunosuppression.
Important preventive measures include:
• Practising regular hand hygiene
• Avoiding close contact with individuals who have contagious infections
• Following appropriate food-safety precautions
• Drinking safe and hygienic water
• Maintaining good personal hygiene
• Keeping vaccinations up to date as advised by the transplant team
• Seeking medical advice promptly if symptoms of infection develop
Recipients should also follow the specific infection-prevention recommendations provided by their transplant centre.
A balanced and nutritious diet is an important component of long-term transplant health.
Recipients should aim to:
• Maintain a healthy body weight
• Eat a balanced diet rich in vegetables, fruits, whole grains, and appropriate sources of protein
• Maintain adequate hydration unless fluid restriction has been advised
• Limit excessive salt, sugar, and processed foods
• Exercise regularly according to their medical condition and physician's advice
• Avoid smoking and tobacco products
• Avoid excessive alcohol consumption
Certain foods, supplements, and herbal preparations may interact with immunosuppressive medications. No dietary supplement, herbal preparation, or over-the-counter medication should be started without discussing it with the transplant team.
Living organ donation is a remarkable act of generosity. However, protecting the donor's long-term health remains the highest priority.
After donation, the donor should remain under appropriate medical supervision and follow the recommendations of the transplant and surgical team.
The recovery period varies depending on the type of donation and the individual's overall health.
Donors should:
• Follow wound-care instructions carefully.
• Take prescribed medications as directed.
• Get adequate rest during the initial recovery period.
• Gradually resume physical activity as advised.
• Avoid strenuous exercise and heavy lifting until medically cleared.
• Return to work and normal activities progressively.
The recovery process should be individualized rather than based solely on a fixed timeline.
Most carefully selected kidney donors can lead healthy, active lives with a single functioning kidney.
Long-term health recommendations include:
• Maintaining a healthy body weight
• Exercising regularly
• Eating a balanced diet
• Staying adequately hydrated
• Avoiding tobacco
• Avoiding unnecessary use of potentially kidney-toxic medications, particularly certain painkillers such as NSAIDs
• Monitoring blood pressure
• Periodically checking kidney function and urine as recommended
Living donation should never mean that donors stop looking after their own health. The donor's well-being remains a lifelong priority.
Any new or persistent symptoms should be reported to a healthcare professional.

Transplantation and organ donation can have a significant emotional impact on both recipients and donors.
Recipients may experience anxiety related to rejection, medication, financial concerns, or the uncertainty associated with transplantation. Living donors may also experience emotional changes during the recovery period.
Maintaining open communication with family members and the transplant team can be extremely helpful. If persistent anxiety, depression, sleep disturbances, or emotional distress develops, professional psychological or psychiatric support should be sought.
The success of organ transplantation depends not only on the surgical procedure but also on long-term post-transplant care.
For recipients, medication adherence, regular monitoring, infection prevention, and a healthy lifestyle are essential to preserving graft function.
For living donors, appropriate postoperative recovery, long-term health monitoring, and healthy lifestyle practices help ensure that they continue to live healthy and fulfilling lives after donation.
The transplant may be a single surgical event—but maintaining the gift of life is a lifelong journey.
With appropriate medical supervision, adherence to treatment, healthy lifestyle choices, and timely attention to warning signs, organ recipients can protect the health of their transplanted organ, while living donors can continue to enjoy a healthy and active life after their selfless contribution.

Organ donation is one of the most generous gifts a person can give. Age, diabetes, hypertension or other medical conditions do not automatically rule out organ donation, doctors said on World Organ Donation Day.
Observed on August 13 every year, World Organ Donation Day aims to raise awareness about the need for organ and tissue donation and honour donors and their families.
Dr. Umesh Gupta, Director and HOD, Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, told HealthandMe that organ donation can be considered when brain function is permanently lost and cannot be restored.
Brain death occurs when all functions of the brain and brainstem have permanently stopped.
“Brain death is different from a coma or a prolonged unconscious state. In brain death, the person cannot regain consciousness or breathe independently. Mechanical support may continue to keep the heart beating and preserve the condition of organs for a limited period, which is why organ donation can be considered,” he said.
Depending on the donor’s medical condition, organs such as the heart, liver, kidneys, lungs and pancreas may be suitable for transplantation.
Age alone does not rule out organ donation. Eligibility is assessed individually by the transplant team.
Doctors evaluate:
Can People With Diabetes or Hypertension Donate?
People with well-controlled diabetes or hypertension may still be eligible to donate certain organs or tissues, said Dr. Shailesh Chandra Sahay, Senior Director - Urology, Kidney Transplant, Robotic Surgery, Max Super Speciality Hospital, Patparganj.
Modern transplantation practices allow doctors to assess each organ individually rather than excluding a donor solely because of age or a particular diagnosis.
Every potential donor deserves a medical evaluation. An organ that may appear unsuitable to a person could ultimately give another patient a second chance at life.
Blood group compatibility is an important consideration in organ transplantation.
“A blood group O donor typically donates to O recipients, while AB recipients can receive organs from all ABO blood groups in many transplant settings,” Dr. Saurabh said.
However, compatibility involves more than blood type. Doctors also assess:

Lung cancer has long been associated with smoking, but this is no longer the complete picture. While tobacco remains the leading cause, an increasing number of people who have never smoked are also being diagnosed with the disease. This changing pattern highlights the need to look beyond smoking alone when considering lung cancer risk.
In non-smokers, lung cancer is often diagnosed later because neither patients nor families may initially suspect the disease. As a result, symptoms are sometimes mistaken for common respiratory illnesses, delaying evaluation and treatment.
While smoking continues to account for most lung cancer cases, several other factors can also contribute. Long-term exposure to second-hand smoke, air pollution, radon gas, asbestos, diesel exhaust, and certain workplace chemicals has been linked to an increased risk. A family history of lung cancer or specific genetic mutations may also make some individuals more susceptible, even if they have never used tobacco.
In urban areas, prolonged exposure to polluted air is becoming an important concern. Fine particulate matter can enter deep into the lungs, causing long-term inflammation and damage that may increase the risk of developing lung disease, including cancer.
Early lung cancer may not cause noticeable symptoms. When symptoms do appear, they should not be ignored, particularly if they persist for more than a few weeks. Symptoms that should be evaluated by a doctor include:
• A persistent cough that does not improve
• Coughing up blood
• Chest pain
• Shortness of breath
• Unexplained weight loss
• Repeated chest infections
• Hoarseness of voice
• Persistent fatigue
These symptoms can occur due to several conditions and do not always indicate lung cancer. However, persistent or worsening symptoms should be assessed promptly to identify the underlying cause and begin appropriate treatment if needed.
Finding lung cancer at an early stage improves the chances of successful treatment. Individuals with prolonged exposure to environmental or occupational risk factors, or those with a strong family history of lung cancer, should discuss their risk with a doctor. Imaging tests such as chest CT scans and, when indicated, molecular testing help identify the type of lung cancer and support treatment planning.
Not every case of lung cancer can be prevented, but reducing exposure to tobacco smoke, avoiding harmful occupational exposures, improving indoor air quality where possible, and seeking medical advice for persistent respiratory symptoms can help protect lung health. Greater awareness that lung cancer can affect both smokers and non-smokers may lead to earlier diagnosis, timely treatment, and better outcomes.
