Imagine this. A young teenager, 17, years old, who is fully developed. Now imagine this, the same teenager has a fully developed extra set of limbs and a pelvis. That extra set of pair is attached with chest artery. But, how can this happen?

While it is extremely rare, and has a chance of less than one case occurring per 100,000 births. Such things do happen. This is called parasitic twin.

What Is A Parasitic Twin?

It is an extremely rare type of cojoined twin where a baby is born with an underdeveloped twin attached to its body. This condition is also known as vestigial twins. The condition is very closely related to conjoined twins, where babies are connected at birth and share organs. However, the main difference is that in conjoined twins, there are two developed babies, whereas in parasitic twins, only one is fully developed, other one is underdeveloped and non functional.

In such a case, the twin who is developed is medically known as the autositic or the dominant twin. The dominant twin is healthy in most aspect but may have extra tissue, organs, or limbs from the parasitic twin.

The parasitic twin may be attached with the dominant twin through several places. The common joints are at the head, torso, chest, pelvis, buttocks, or back. In these cases, the parasitic twin is not alive and they die either in the womb or during the childbirth.

Doctors Remove Parasitic Twin

Now, let's go back to the case we referred to, where a young teenager had an extra pair of limbs attached to chest. The teenager who has not been named is from Uttar Pradesh's Unnao neighbourhood, and was treated in AIIMS, Delhi. The team of doctors successfully removed the extra set of limbs from his body.

Dr Asuri Krishna, who led the team of specialist who surgically removed the extra limbs told the BBC that only 40 to 50 cases of parasitic twins have been documented in world medical literature, and in those cases, the surgery had been attempted on children. The doctor said that without much medical literature to guide them, the team of doctors depended on "intuition, skill and knowledge".

The doctor shared that the child had two fully formed legs, buttocks and external genitalia, which weighed around 15kg "protruding from his abdomen".

How Was The Surgery Performed?

The doctor shared that first they identified how interconnected the parasitic and host twins were. The doctors took scans and found that parasitic twin was attached to the teen's breastbone. The blood was being supplied from a vessel in his chest. However, "there wasn't much connection with other main organs like the liver or kidneys," said Dr Krishna. The team also found a large cyst in the teen's abdomen.

Then the surgery was performed in two stages. In the first stage, the parasitic twin was removed. Then the cystic mass was extracted from the surrounded area. The entire surgery was completed in two and a half hours and the team of doctors included radiologists, anaesthetists, and plastic surgeons.

The biggest challenge was when the teen's blood pressure dropped as 30 to 40% of his blood flowed to the parasitic twin, however, the doctors were prepared for it and they stabilized him.

Medical tourism is no longer just a trend—it's becoming a practical choice for millions of people worldwide. Whether it's traveling abroad for an affordable heart surgery, a dental implant, cosmetic procedures, or fertility treatment, more patients are exploring healthcare beyond their home countries.

But is medical tourism always a good idea? While it can offer significant savings and quicker access to treatment, it also comes with important risks that patients should understand before booking a flight.

What Is Medical Tourism?

Medical tourism refers to traveling to another country to receive medical treatment. People often choose this option because healthcare services may be less expensive, waiting times may be shorter, or certain treatments may not be easily available in their own country.

Popular destinations include countries such as India, Thailand, Turkey, Singapore, Mexico, and South Korea, each offering specialized medical services ranging from orthopedic surgeries to cosmetic procedures.

Benefits Of Medical Tourism

One of the biggest reasons people seek treatment abroad is cost. In many cases, medical procedures can cost significantly less than they would in countries with expensive healthcare systems, without necessarily compromising on quality.

Another major advantage is faster treatment. Patients who face months-long waiting lists for surgeries at home may be able to receive care within days or weeks overseas.

Understanding The Risks

Despite its advantages, medical tourism isn't without challenges.

Healthcare standards, regulations, and infection-control practices vary from country to country. Patients may also face language barriers, making communication with healthcare providers more difficult.

Follow-up care is another important concern. If complications develop after returning home, local doctors may have limited information about the treatment performed abroad, making recovery more complicated.

Long-distance travel soon after surgery can also increase the risk of complications such as blood clots, particularly after major operations.

Additionally, legal protections differ between countries. If something goes wrong during treatment, seeking compensation or resolving medical disputes may be more difficult than in your home country.

How To Stay Safe

Experts recommend researching hospitals carefully before making any decisions. Look for internationally accredited healthcare facilities, experienced specialists, and verified patient reviews.

Patients should also request detailed information about the procedure, possible complications, recovery timelines, and total costs—including unexpected expenses.

Before traveling, discuss your plans with your primary healthcare provider. They can help determine whether traveling for treatment is appropriate and advise you on vaccinations, medications, and post-treatment follow-up.

Finally, purchase travel insurance that specifically covers medical procedures abroad if available, as standard travel insurance policies may exclude elective treatments.

Our role as cardiologists involves observing young athletes train hard to become the next footballer or cricket player. Maintaining a strong and healthy heart requires more than just lung capacity for endurance in tasks like completing '90-minute pitch sprints' or preparing to go through gruelling five-day test matches.

Although uncommon, young athletes often face serious cardiac events that can be prevented. Why? Start your day with habits that can protect your heart.

Vital Heart Habits For Aspiring Athletes

Before competing in a competitive sport, it is important to conduct introductory cardiac evaluations. Set priorities accordingly. If a family history includes sudden cardiac death, cardiomyopathy, unexplained fainting, or inherited heart disease, hypertrophic cardiomyopathies can be detected early on by examining the body through symptom-specific ECG and personal/family history testing.

The process of dehydration causes your heart to pump faster and requires a much greater amount of blood. Consuming water on a daily basis and using electrolyte solutions during intense sweat sessions can prevent arrhythmias.

Don't overlook symptoms like chest tightness, sudden shortness of breath, or faintness when exercising; these are not just fatigue but signs of fatigue. Go and see a medical professional without delay.

Prosperity for recovery and sleep: Deep sleep is characterized by a decrease in heart rate, a settling of blood pressure, and relaxation of cardiac muscle tissue. By sacrificing 8-9 hours of sleep, your heart will become affected, and stress hormones such as cortisol are elevated.

Avoid consumption of energy drinks that contain harmful stimulants and high levels of caffeine, as it can lead to heart palpitations. Consume whole foods high in lean protein and complex carbohydrates.

“Dreaming big requires training smart. If you listen carefully and respect your heart today, it will be enough for years to make sure you can continue playing sports.”

Worldwide, more than 57 million people live with dementia, experiencing symptoms such as short-term memory loss, difficulty finding words, confusion about time or place, trouble with complex tasks, and changes in mood or personality. Around 10 million new cases are diagnosed every year.

Recent studies suggest that the average lifetime risk of developing dementia after age 55 is about 42%.

A new study has found that maintaining healthy blood pressure, controlling blood sugar, and avoiding smoking during middle age could significantly reduce the risk of developing dementia.

People who maintained these three health measures between the ages of 48 and 68 lived, on average, nearly 13 additional years without dementia, according to the study published in the journal Neurology Open Access.

"Our findings argue that people need to actively avert these factors in midlife as a strategy for preserving brain health for more than a decade," said study senior investigator Josef Coresh, Professor in the Department of Population Health at NYU Langone.

"Discovering new ways to delay dementia is crucial with 42% of Americans at risk for developing the condition at any time after age 55," he added.

How Was the Study Conducted?

Researchers analyzed data from the Atherosclerosis Risk in Communities (ARIC) Study, an ongoing community-based study that began in 1986. It has tracked participants for decades, measuring midlife vascular risk factors and the development of dementia.

The analysis included 12,409 adults with an average age of 56, all of whom were free of dementia at the start of the study. Researchers assessed three key risk factors:

• High blood pressure
• Diabetes
• Smoking

• 3,008 people developed dementia.
• 5,238 died without developing dementia.

Key Findings

Researchers also examined how midlife cardiovascular risk factors affected dementia-free survival across different demographic groups.

Among participants with all three risk factors:

• Women lived an average of 18.1 years without developing dementia, compared with 16.6 years for men.
• White participants lived an average of 19.6 years without dementia, compared with 16.0 years for Black participants.

"Hopefully, these results will encourage people to stop smoking and watch their vascular health closely from age 48 on."

What Is Dementia?

Dementia is an umbrella term for a significant decline in mental function that interferes with daily life. It commonly affects memory, thinking, and reasoning abilities and is caused by underlying conditions such as Alzheimer's disease or vascular dementia.

While there is currently no cure, the WHO says up to 45 per cent of dementia risk can be prevented or delayed by addressing modifiable risk factors such as tobacco and alcohol use, physical inactivity, social isolation, air pollution, and noncommunicable diseases (NCDs), including high blood pressure and diabetes.
