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.

Naturopath and health educator Barbara O'Neill believes many of the foundations of good health are simple, inexpensive, and often overlooked.

In an interview with HealthandMe, she spoke about her journey into natural healing. Barbara said her interest began when she was looking for alternatives to repeated medication use for her children.

"I was pulled towards natural healing because I didn't want to give my children drugs," she said, recalling how her first child underwent four courses of antibiotics within six weeks.

That experience prompted her to explore other ways of managing common health issues such as earaches and discomfort.

On Ayurveda And Traditional Healing

Barbara said she sees similarities between her philosophy of health and Ayurveda. "I believe that there's a lot of similarities between what I believe," said the 72-year-old, adding that she supports approaches that work and do not cause harm.

While acknowledging that medicines can save lives in emergencies, she argued that long-term healing depends on creating the right conditions for the body.

"Yes, in a crisis, a drug may save a life, but drugs can't heal us. That's why it's time to go back to the old ways," she said.

According to Barbara, understanding how the body functions is key to understanding healing.

"When you understand how they function, then you begin to understand what they need. And if you give the body the right conditions, the healing will accelerate," she told HealthandMe.

The Healthy Habits

Barbara said that sleep, hydration, exercise, and natural foods are key to better health. She also called out modern lifestyles, which often encourage people to stay awake too late, particularly because of technology; and recommended getting enough sleep.

"Start going to bed earlier and aiming for eight hours sleep a night," she said.

Barbara also emphasized daily movement, whether through running, walking, push-ups, squats, or stretching.

"Every day, I make a point of moving my body," she said.

Why Barbara O'Neill Doesn't Take Supplements

At a time when supplements have become a multi-billion-dollar industry, Barbara revealed that she does not take any supplements herself.

"I take no supplements," she said, noting that she advocates focusing on fundamental health habits.

"What should be there instead is exercise every day, eating food in its natural state, drinking adequate water, and going to bed early," she said.

While she is not opposed to supplements, she believes they are often unnecessary.

"There are times where they may be necessary, but most of the time we don't need them," she added.

Natural Food And Stress Management

Barbara also encouraged people to eat foods in their natural state and suggested a simple dietary habit for Indians.

"Eat dal every day," she said.

For stress management, she said both sleep and meditation are important. She described beginning each day with prayer, reflection, and quiet time.

Barbara said that the human body has an innate ability to heal when supported by healthy habits.

"I want people to remember that they live in a body that can heal. So please look after it," she told HealthandMe.

Many working women who are pregnant tend to dismiss signs such as headaches, swelling, or vision changes, thinking that they are common during pregnancy. However, these issues can be caused by preeclampsia, a serious condition that requires timely attention, especially among busy working women.

What is preeclampsia?

Dr Prachi Sarin Sethi, Senior Consultant – Obstetrician, Gynaecologist & Laparoscopic Surgeon, Motherhood Hospitals, Gurgaon, said, "Pregnancy comes with many physical changes, and it is common for women to experience discomfort such as swelling, fatigue, or headaches. However, sometimes these symptoms may point to something more serious, namely preeclampsia, a pregnancy-related condition that can affect both the mother and baby. Working women tend to ignore the signs of this condition and struggle in silence. Preeclampsia is a condition that usually develops after the 20th week of pregnancy. It is mainly characterised by high blood pressure and can affect organs such as the liver and kidneys. If not managed in time, it can lead to serious complications for both mother and baby."

What are the causes of preeclampsia?

The exact cause of preeclampsia is not known. Certain factors increase the risk, including:

1. High blood pressure before pregnancy
2. First pregnancy
3. Multiple pregnancies (twins or more)
4. Obesity or diabetes
5. High stress levels and lack of rest

What are the symptoms of preeclampsia?

Many symptoms of preeclampsia are mistaken for normal pregnancy changes. These include:

1. Persistent headaches
2. Swelling in the face, hands, or feet
3. Blurred vision or light sensitivity
4. Sudden weight gain
5. Pain in the upper abdomen

Consequences of untreated preeclampsia

Working women may ignore these signs due to work pressure, long hours, or frequent travel, assuming they are just tired or stressed. If left untreated, preeclampsia can lead to serious complications such as:

1. Preterm delivery
2. Low birth weight of the baby
3. Organ damage in the mother
4. Seizures (a severe condition called eclampsia)

Early detection and proper care can help manage the condition and reduce risks.

This is why working women miss the signs

In today’s fast-paced lifestyle, many women continue working through pregnancy without slowing down. Long working hours, stress, irregular meals, and lack of rest tend to worsen symptoms. Many women delay check-ups or ignore warning signs, thinking they are minor issues.

What can women do?

Report any signs and symptoms, such as headaches and vision changes, to a doctor. De-stress by practising yoga and meditation. Monitor blood pressure regularly, avoid overexertion, and maintain a balanced diet consisting of fresh fruits, vegetables, whole grains, and pulses. Avoid junk, oily, and canned foods. It is also necessary to stay hydrated, attend regular health check-ups, and follow-up appointments.

Osteoarthritis (OA), long considered a “wear-and-tear” disease of old age, is increasingly being diagnosed in people as young as 30, according to new research.

The review by researchers at Indraprastha Apollo Hospitals suggests OA should be viewed as a heterogeneous syndrome rather than a single disease. The condition is driven by a combination of biological, biomechanical, metabolic, genetic, and molecular factors, but in youth obesity and poor lifestyle is surging the cases.

“Osteoarthritis is no longer confined to the elderly — we are now seeing patients as young as 30, often driven by obesity and sedentary lifestyles. This research makes clear that osteoarthritis is not a single disease but a spectrum of conditions,” said Dr. (Prof.) Raju Vaishya, Senior Consultant Orthopaedic and Joint Replacement Surgeon, Indraprastha Apollo Hospitals.

Noting that a one-size-fits-all approach may not help, the expert stressed the need for personalized treatment that recognizes the specific phenotype in each patient.

Six Disease Subtypes Identified

The review, published in International Orthopaedics, identifies six disease subtypes, including inflammatory, metabolic, and pain-sensitization variants. Researchers recommend MRI-based tools and biomarker panels to guide treatment decisions.

Emerging technologies such as AI-assisted MRI scoring and PET-MRI with 18F-NaF may also enable earlier detection and better patient classification, although wider clinical adoption will require standardized protocols and large-scale validation studies.

Osteoarthritis Burden Rising Worldwide

More than 500 million people worldwide live with osteoarthritis, accounting for 7.6 per cent of the global population. According to Global Burden of Disease estimates, prevalence has increased by 132 per cent over the past 30 years and is projected to rise by another 60 per cent by 2050.

Women, people with obesity, and those with previous joint injuries are disproportionately affected.

Osteoarthritis occurs when the cartilage that cushions the ends of bones gradually wears down, causing joints to become stiff, painful, and less mobile.

The disease commonly affects the knees, hips, and small joints of the hands, although it can occur in almost any joint.

Common symptoms include:

• Joint pain
• Joint stiffness
• Difficulty moving affected joints
• Swelling
• Joint tenderness
• A grating or crackling sensation during movement
• Pain and stiffness after periods of inactivity
• Enlarged or knobbly joints
• Reduced range of movement
• Muscle weakness or muscle loss

How To Prevent Osteoarthritis

Experts say maintaining a healthy weight, staying physically active, avoiding prolonged sedentary behaviour, and preventing joint injuries can help lower the risk of osteoarthritis.

One of the biggest challenges in osteoarthritis treatment is the “care gap.” Many patients are too young or not yet severe enough for surgery but may spend years relying on medications that relieve symptoms without addressing the underlying mechanics of joint stress.

Research suggest gait retraining — adjusting the way a person walks — could help bridge this gap. Unlike medication or surgery, gait retraining is non-invasive and may offer a sustainable long-term solution.

Currently, gait retraining often requires specialized tools such as motion-capture systems and pressure-sensitive treadmills. However, newer approaches, including smartphone-based video analysis and sensor-equipped “smart shoes,” are being developed to make the technique more accessible.

Experts caution against making major changes to walking patterns without professional guidance, as improper adjustments may place additional strain on other parts of the body.
