Singer Jesy Nelson recently shared an emotional update regarding the complications she is experiencing in her pregnancy with twin babies. Former Little Mix singer Jesy, who is having twins with partner Zion Foster, announced that she has been diagnosed with pre-twin-to-twin transfusion syndrome (pre-TTTS). The condition, which is present in pregnancies involving twins with a shared placenta, has serious risks involved and needs intense medical supervision. As Nelson embarks on this difficult journey, her story enlightens us about a rare but dangerous condition many expectant parents may not know much about.
Twin-to-twin transfusion syndrome is a rare but dangerous condition that arises in monochorionic twin pregnancies, in which identical twins share a single placenta. The placenta supplies the developing babies with oxygen, nutrients, and blood flow, but in TTTS, there is an imbalance of blood vessels that interconnect the twins, and thus the vital resources are not evenly distributed. One twin, or the donor twin, shares excess blood with the other, referred to as the recipient twin. This leads to one baby becoming malnourished and possibly anemic, and the other in danger of heart problems due to too much blood.
Nelson described her diagnosis in a heartfelt Instagram video, explaining that she is currently in the pre-stage of TTTS and undergoing frequent monitoring. "I am being scanned twice a week, and each time, things have gotten a little worse," she shared, expressing her fears and hopes for the health of her babies.
If left untreated, TTTS can have devastating consequences. Medical research indicates that:
TTTS usually advances in stages, beginning with minimal changes in fluid levels and worsening as one twin continues to get an unequal share of blood. In extreme cases, fetal laser surgery, referred to as the Solomon technique, can be employed to divide the blood vessels and balance the twins.
Identical twins may develop differently, and their own unique form of placental sharing can have a dramatic effect on pregnancy risk. Jesy Nelson's twins are considered monochorionic diamniotic (mono/di), which means they share a placenta but have two amniotic sacs. This is the type of pregnancy in about 70% of identical twin pregnancies and carries an increased risk of complications like TTTS, umbilical cord entanglement, and growth restriction.
Conversely, dichorionic diamniotic (di/di) twins both have a separate placenta and amniotic sac, which greatly diminishes the threat of TTTS. Twin pregnancy type is normally identified by early ultrasound, with physicians being able to track future complications from inception.
Twin pregnancies, even without the presence of TTTS, entail a variety of health risks to the mother as well as infants:
Over 60% of twin pregnancies end in premature delivery, with birth usually taking place before 37 weeks. Premature infants can have immature organs and need neonatal intensive care (NICU) assistance to assist with breathing, feeding, and infection fighting.
Pregnant women with multiples are at increased risk of having high blood pressure during pregnancy. This, if left untreated, can result in preeclampsia, a serious complication of pregnancy that can result in damage to organs, preterm labor, and in some cases, maternal or fetal death.
Pregnant women carrying multiples are twice as likely to experience anemia, a condition where the body does not produce enough healthy red blood cells. This can lead to fatigue, dizziness, and complications during delivery.
According to John Hopkins Medicine, multiple birth babies are twice as likely to have congenital abnormalities compared to single births. These can include heart defects, neural tube defects, and gastrointestinal issues.
When twins have to share a placenta, they are more likely to have polyhydramnios (excess amniotic fluid) or oligohydramnios (not enough amniotic fluid). Both result in distress to the babies during fetal development and can result in premature labor.
Twins are at increased risk of excessive postpartum hemorrhage because their uterus is larger and there are greater blood supply needs.
Jesy Nelson's openness about her challenging experience is raising awareness for TTTS, a condition that few individuals—let alone expectant mothers and fathers—might be aware of. Through her tearful video, Nelson stressed the significance of knowing about twin pregnancies aside from the thrill of having multiples. "We had no idea that this type of thing occurs when you're having twins. We just desperately want to make people aware of this because there are so many people who aren't aware."
Her case reminds us of the intricacies involved in twin pregnancy and the significance of early identification and medical management. For mothers carrying twins, frequent ultrasounds and vigilance can become a life-and-death issue for early detection and better outcomes of both babies.
Through constant medical attention and care, she and her partner Zion Foster remain positive and get ready for their babies to be born. In other parents whose situations are no different, the story of Nelson highlights awareness, medical progress, and emotional encouragement in handling complicated pregnancies.
The expecting parents of twin siblings are advised to discuss TTTS screening and possible interventions with their physicians to give their babies the best chance.

Night shift workers often face the risks of poor sleep or sleep deprivation. They have long been advised to aim for one uninterrupted block of daytime sleep after work.
However, a new review suggests that splitting sleep into two separate periods, known as biphasic sleep, can help them avoid certain health risks.
Night shifts have become an unavoidable part of our lives. Healthcare professionals, emergency responders, factory employees, and transportation workers often work overnight.
Night shifts can disrupt the body's internal clock, increasing the risk of obesity, diabetes, cardiovascular disease, depression, and cognitive decline.
Research also shows that night shift workers typically sleep one to four hours less than daytime workers, leading to chronic sleep debt over time.
The recent review, published in the journal Sleep Medicine Reviews, examined existing research on biphasic sleep among shift workers.
Researchers found that while evidence is still emerging, dividing sleep into two episodes can help workers get more sleep, improve alertness during night shifts, and potentially reduce a few long-term health risks associated with chronic sleep deprivation.
The researchers noted that although sleep recommendations traditionally focus on obtaining one long sleep period, many shift workers naturally divide their sleep into two episodes. They usually sleep for a few hours immediately after work and then take another longer sleep before returning for the next night shift.
"Biphasic sleep may help mitigate sleep loss-related impairments," the authors wrote, while observing that its potential benefits have not been fully understood until now.
According to the review, this split-sleep pattern could help workers accumulate more total sleep over a 24-hour period while fitting better around their daytime commitments.
Evidence also suggests biphasic sleep may improve alertness, reduce fatigue, and enhance cognitive performance compared to one uninterrupted daytime sleep, which is often shortened and disrupted by noise, light, or social obligations.
The findings build on a growing body of research suggesting that sleep does not necessarily have to occur in one continuous block to provide health benefits.
A 2025 review also stated that biphasic sleep may be a natural and flexible sleep pattern for some people and could be particularly useful for shift workers, new parents, and others facing unavoidable sleep disruption.
Experts do caution that split sleep is not a permanent solution. The latest review emphasizes that evidence is still limited as there are just a few reliable studies that directly compare biphasic and monophasic sleep among night workers.
Factors like shift schedules, chronotype, workplace demands, and individual health conditions can all influence whether the strategy is effective.
Sleep specialists also stress that the total amount of sleep remains the most important factor.
Adults should still aim for seven to nine hours of sleep within a 24-hour period whenever possible. Good sleep hygiene, including using blackout curtains, reducing noise, avoiding caffeine before bedtime, and maintaining a consistent sleep schedule, continues to play a key role in protecting long-term health.

A new study suggests that rising temperatures, floods and droughts could affect the predictability and frequency of waterborne disease outbreaks. Climate change can alter the traditional patterns of disease transmission in ways that are more complex than previously understood.
Researchers state that public health systems can no longer rely on existing weather-disease relationships, as global warming has significantly changed the environmental conditions and their influence how pathogens survive, spread and infect people.
The review says that increasing temperatures, extreme rainfall, prolonged droughts and flooding do not simply increase disease risk. Instead, they can alter the timing, intensity and location of outbreaks, making them less predictable.
"Climate change is resetting many of the environmental conditions that determine when and where waterborne diseases emerge," the researchers noted, emphasizing that disease surveillance systems must evolve to keep pace with these changing dynamics.
According to the researchers, several climate-related factors work together to increase the likelihood of contaminated water and disease transmission.

Warmer water allows bacteria, viruses and parasites to multiply more rapidly. Pathogens such as Vibrio cholerae, which causes cholera, thrive in warmer aquatic environments.
Extreme rainfall can overwhelm sewage systems and contaminate drinking water with human and animal waste. Floodwaters also spread pathogens into rivers, lakes and groundwater supplies.
Although drought reduces water availability, it can also increase disease risk. Limited water supplies often become more concentrated with pathogens, while communities may be forced to use unsafe water sources.
Storms, cyclones and floods frequently damage sanitation infrastructure, creating conditions where waterborne infections can spread rapidly.
These factors interact in different ways depending on geography, infrastructure and local climate, making future outbreaks increasingly difficult to forecast.

Researchers say climate-sensitive waterborne illnesses include:
Children, older adults and people living in regions with limited access to safe drinking water and sanitation are expected to face the greatest risks.
The researchers stress that instead of reacting to outbreaks the governments should strengthen climate-friendly public health systems. The key recommendations include:
Researchers say that understanding the evolving relationship between climate and infectious diseases will be essential to protecting communities across the world as global temperatures continue to rise.
Climate change is increasingly being recognized as a major public health threat, extending beyond heatwaves and air pollution to affecting patterns of infectious diseases.
The new review suggests that future waterborne disease outbreaks may not simply become more frequent but also less predictable, requiring health systems to adapt quickly to a changing climate.
As extreme weather events become more common worldwide, researchers warn that protecting safe water supplies and strengthening surveillance will be critical to reducing the growing burden of waterborne diseases.

Nearly nine out of every 10 Indian adults have at least one abnormal blood lipid level, according to a recent nationwide study by ICMR-INDIAB.
The findings highlighted a massive looming public health crisis that could increase the risk of heart attacks, strokes and other cardiovascular diseases across the country in the near future.
The findings, which were reported between July 17 and July 19, 2026, reveal that dyslipidemia, an unhealthy imbalance of cholesterol and triglycerides in the blood, affects an alarming number of Indian adults.
Despite being preventable and treatable, the condition often remains undiagnosed because it presents with little to no symptoms until serious complications surface.
The study was conducted by the Indian Council of Medical Research’s India Diabetes (ICMR-INDIAB) in what is one of the country’s largest community-based metabolic health surveys, involving over 113,000 adults from different states and Union Territories.
According to the study, women, those living in urban areas, and residents of Central India carried a disproportionately higher burden of abnormal lipid levels.
Researchers also found that dyslipidemia was significantly more common among people with prediabetes or diabetes, obesity, and hypertension.
These metabolic conditions substantially increasing the risk of various cardiovascular diseases and complications.
Dyslipidemia refers to unhealthy levels of fats circulating in the bloodstream. These include:
ICMR-INDIAB programme has already shown that lipid disorders remain one of the concerning health risks. However, the latest study highlights just how serious the problem has become, with nearly 90% of adults exhibiting at least one lipid abnormality.
Factors like rapid urbanisation, sedentary lifestyles, unhealthy diets, obesity and rising diabetes rates are likely contributing to the worsening burden of cholesterol.
Unlike many chronic diseases, dyslipidemia can be managed through early detection and lifestyle change. Doctors recommend the following preventive measures:
India has witnessed a steady rise in metabolic disorders over the past two decades, with cases of diabetes, obesity, hypertension and abnormal cholesterol increasingly surging.
Researchers warn that unless preventive measures are strengthened and strict lifestyle changes adopted, the country could face an even greater burden of heart disease and other related disorders in the future.
