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.

Amid rising global infertility rates, a new study has found that an imbalance in the bacteria present in men's semen may reduce a couple's chances of having a baby and increase the risk of pregnancy loss. Researchers also found that the composition of women's gut bacteria may influence fertility outcomes.
The study, published in The Lancet Obstetrics, Gynaecology & Women's Health, found these associations were particularly evident among couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), as well as those with a history of recurrent pregnancy loss.
Researchers from the University of Copenhagen, Denmark, said the findings point to "imbalances in men's semen and in women's gut bacteria as previously overlooked and potentially treatable risk factors for infertility and recurrent pregnancy loss."
Although the vaginal microbiome has been studied extensively in relation to fertility, the gut and seminal microbiomes have been largely overlooked.
“Incorporation of couple-level microbial assessment might represent a novel approach for targeted therapeutic strategies,” the team said.
The researchers followed 353 women and 191 of their male partners between April 2018 and September 2023. All participants were heterosexual couples undergoing fertility treatment or had experienced recurrent pregnancy loss.
They analyzed bacterial communities in the women's gut and vagina and in the men's semen before tracking pregnancies and birth outcomes. About one in four men had an unhealthy bacterial imbalance, known as dysbiosis, in their semen.
Among couples undergoing IVF or ICSI:
The researchers also noted that standard semen analysis cannot detect this bacterial imbalance, meaning a man's test results may appear normal even when dysbiosis is present.
The study found that an imbalance in women's gut bacteria was associated with:
However, gut bacterial imbalance was not associated with miscarriage, while an imbalance in vaginal bacteria showed no clear link with either infertility or pregnancy loss.
According to the researchers, assessing the microbiome in both men and women could improve infertility evaluation and help identify previously overlooked, potentially treatable factors affecting fertility.
They added that, if confirmed in larger studies, therapies aimed at restoring healthy bacterial balance in semen and the gut could improve fertility outcomes and reduce recurrent pregnancy loss.
Infertility is a disease of the male or female reproductive system, defined as the inability to achieve pregnancy after 12 months or more of regular, unprotected sexual intercourse.
According to the World Health Organization (WHO), one in six people globally experience infertility during their lifetime. The condition can cause significant emotional distress, social stigma and financial hardship, with far-reaching effects on mental and psychosocial well-being.

An artificial intelligence (AI)-powered blood test has accurately detected liver cancer in patients from two geographically and biologically distinct populations.
It is being considered a breakthrough that can help researchers develop accessible and effective screening for people at high risk of the disease.
The study by researchers from Johns Hopkins University, validated an AI-based blood test in 377 participants from Guatemala and Romania, two populations with different genetic backgrounds and major causes of liver disease.
The findings suggest the technology may be effective across diverse populations. It marks an important step in deploying AI in real-world clinical use.
The test is based on DELFI (DNA Evaluation of Fragments for Early Interception), an AI platform that analyses patterns in cell-free DNA fragments circulating in the bloodstream.
Rather than searching for a single mutation, the algorithm detects subtle changes in how DNA is fragmented, which is a sign of cancer.

Researchers found that when the DELFI blood test was combined with the commonly used liver cancer biomarker alpha-fetoprotein (AFP), along with a patient's age and sex, it detected 89% of liver cancers overall and 79% of early-stage cancers.
This was significantly better and effective than AFP testing alone, which has limited sensitivity for detecting tumours at an early stage.
The study also provided new insights into why the test performs well, showing that DNA fragmentation patterns carry biological signals linked with liver cancer across different patients from different backgrounds.
According to the researchers, this strengthens confidence that the AI technology could be applied beyond a single country or healthcare setting and can be used to improve liver cancer detection systems.

Healthy and cancerous cells release tiny fragments of DNA into the bloodstream. The DELFI platform uses AI to examine the size, distribution, and genomic patterns of these fragments.
Instead of looking for a specific mutation, it recognises fragmentation signs that indicate the presence of liver cancer, making it possible to identify the disease using just a simple blood sample.
While the findings are promising, the researchers emphasised that the test is not yet ready for routine clinical use.
Larger human clinical studies will be needed before it can become part of standard liver cancer screening programmes.
If future trials confirm these results, AI-powered blood tests could become a valuable addition to current cancer detection processes, helping doctors detect liver cancer earlier and improving outcomes for people at highest risk.

Hepatocellular carcinoma (HCC), the most common type of liver cancer, is often diagnosed only after symptoms develop, reducing the chances of successful treatment.
People living with cirrhosis, chronic hepatitis B or hepatitis C infection, and metabolic dysfunction-associated steatotic liver disease (MASLD) are at particularly high risk of contracting this disease.
The existing screening methods, including ultrasound and AFP testing, can miss early cancers, while access to imaging is limited in many parts of the world.
A blood-based test that performs consistently across diverse populations could help improve screening and identify cancers when they are still treatable.

From weight loss and diabetes to cancers and much more, GLP-1 drugs have delivered blockbuster results and transformed treatment for millions of people worldwide.
Clinical data have consistently shown that GLP-1 receptor agonists containing semaglutide and tirzepatide—including Ozempic, Wegovy and Mounjaro—reduce overall mortality as well as the risk of heart-related deaths.
However, reports from the UK and US have linked these medicines to more than 200 deaths. While a direct causal relationship has not been established and millions of people use these medications safely, high-profile inquests and adverse event databases have highlighted reports of deaths in which these drugs were listed as a suspected contributing factor, including cases associated with severe complications, dosing errors, and the use of counterfeit or compounded products.
Data submitted to the UK's Medicines and Healthcare Products Regulatory Agency (MHRA) show a total of 82 deaths associated with glucagon-like peptide-1 (GLP-1) receptor agonists, the class of drugs used to treat obesity and type 2 diabetes, up to January 31, 2025.
The data includes 22 deaths associated with GLP-1 agonists used for weight loss, while 60 deaths were linked to their use in treating type 2 diabetes. As per the MHRA data:
"The decision to start, continue, or stop treatments should be made jointly by patients and their doctor, based on full consideration of benefits and risks," said Alison Cave, MHRA Chief Safety Officer.
In 2026, the deaths of two people in Northern Ireland potentially linked to Wegovy and Mounjaro injections were also reported to the MHRA.
The two cases are among more than 500 suspected adverse drug reaction reports submitted from Northern Ireland over the past two years related to GLP-1 medications.
In the US, Ozempic and Wegovy have been linked to 162 deaths since 2018, according to reports in the FDA's FAERS (FDA Adverse Event Reporting System) database.
While none of the deaths have been proven to be directly caused by semaglutide injections, the reports indicate the drugs were listed as a factor in the fatalities.
Driven by the rising prevalence of obesity and type 2 diabetes, the use of GLP-1 medications such as Ozempic, Wegovy, Mounjaro and Zepbound has increased dramatically in recent years. The global GLP-1 drug market is estimated to reach $200 billion by 2030.
Although each medication has distinct FDA-approved uses, they share four common mechanisms of action:
In June 2026, the FDA raised concerns about patients and healthcare professionals seeking unapproved versions of GLP-1 receptor agonists, including semaglutide and tirzepatide, for weight loss.
The agency warned that unapproved products do not undergo FDA review for safety, effectiveness or quality before being marketed.
The FDA recommends that:
The FDA advises consumers to watch for warning signs, including companies that:
