Weighing in on this, Dr (Prof) Virender Kumar Gehlawat, Consultant - Paediatrics & Head PICU, Manipal Hospital Dwarka, shared with HT Lifestyle about blue baby syndrome, which can mysteriously appear in the early days.
He said, 'For some infants, a mysterious bluish tint in the skin, lips, nails, and mucous membrane appears, signalling a medical emergency - one known as Blue Baby Syndrome. Blue Baby Syndrome is not a disease in itself, but a sign of an underlying medical condition often indicating an underlying cardiac, Pulmonary or haemoglobin-related disorder resulting from insufficient oxygen in a baby's bloodstream, medically known as cyanosis.'

Since the primary cause of Blue Baby Syndrome is a lack of adequate oxygen in the body, parents need to monitor their baby's oxygen levels. As Dr Gehlawat explained,'Detecting cyanosis with the naked eye can be challenging, especially in mild cases, dark-skinned babies, or those with anaemia. Therefore, using a pulse oximeter, a simple device that measures oxygen levels in the blood, is crucial whenever cyanosis is suspected.'
Why does it happen?
'Blue Baby Syndrome occurs when there is insufficient oxygen reaching the body's tissues. This can happen due to three main reasons: heart defects, lung problems, and abnormal haemoglobin, ' Dr Gehlawat opined.
He shared three main reasons which may contribute to the oxygen deficiency:
Heart defects: Congenital heart diseases like Tetralogy of Fallot, transposition of great arteries, or truncus arteriosus may lead to mixing of oxygen-rich and oxygen-poor blood, reducing overall oxygen delivery to the body. Lung problems: Conditions like pneumonia, respiratory distress, or underdeveloped lungs in premature babies can impair oxygen exchange in the lungs, causing cyanosis. Abnormal haemoglobin: Rarely, disorders like methemoglobinemia interfere with the blood's ability to carry oxygen, leading to bluish discoloration even when lungs and heart are normal.
What are the signs and symptoms?
First of all, recognising the symptoms is essential, and can even be life-saving. A baby may seem healthy at birth, but certain symptoms can emerge soon after.
Dr Gehlawat described the symptoms and tests, checks that help in diagnosis, "Babies with TOF may look normal at birth but begin to show signs and symptoms within the first few weeks of life. The classic symptom is bluish discolouration of the lips, tongue, and fingertips, especially during crying or feeding. Some babies experience sudden worsening of cyanosis, known as a 'Tet spell', where the child becomes very blue, breathless, and irritable. A good history, physical examination, 2D-Echocardiogram (heart ultrasound), and other cardiac imaging confirm the diagnosis."
Is it treatable?
While it may seem disheartening when newborns face such serious conditions, Dr Gehlawat offered reassurance and explained that there's hope for recovery. He said, "Yes, Tetralogy of Fallot is a surgically correctable condition. Babies may initially require medications or a temporary surgical procedure to improve oxygenation. Definitive open-heart surgery, usually performed within the first year of life, repairs the structural defects and allows the heart to function normally. With timely intervention, most children go on to live healthy, active lives.'

Radiologist shares 5 common breast cancer signs most women overlook: ‘If it looks like an orange peel, get it checked'
Many women unknowingly overlook subtle signs that could be early indicators of breast health issues. From minor changes in skin texture to unexpected discomfort, these symptoms often go unreported until it's too late. Breast imaging expert highlights subtle signs of cancer patients often ignore. (Pexels) "In my 15 years of experience as a breast radiologist, I've seen countless cases where early warning signs were overlooked or dismissed. While most women diligently check for lumps during self-examinations, I frequently encounter patients who've ignored other critical symptoms for months or even years. As someone who interprets thousands of mammograms and breast imaging studies annually, I want to share the subtle signs that often slip under the radar but deserve immediate attention," says Dr Namrata Singal Sawant, a Mumbai-based senior radiologist. She further shared with HT Lifestyle 5 subtle symptoms you shouldn't ignore and why early detection matters. 1. Changes in breast texture and appearance One of the most significant findings I encounter in my practice is architectural distortion, changes in breast skin texture that many patients attribute to normal ageing. The most common early signs of the same are: Any dimpling or puckering of the skin can suggest an underlying carcinoma pulling the skin or Cooper's ligament. Characteristic orange-peel appearance (peau d'orange) can be a sign of inflammatory breast carcinoma. Shrinking of the size of any one of the breasts. This can be seen in some lobular carcinomas, which are difficult to diagnose. Increase in the size of the breast. We must be aware of the natural asymmetry of our breasts, if any. Any increase in the size of the breast, especially asymmetrical, must be viewed with caution. We must contact our medical professional about this. Nipple changes and lymph node evaluations are often overlooked yet crucial in diagnosing breast cancer.(Pexels) 2. Nipple changes and discharge Nipple changes often provide crucial diagnostic clues that patients initially overlook. Nipple discharge, particularly when unilateral, spontaneous and blood-stained, has led me to identify high-risk lesions and early-stage ductal carcinomas. Nipple retraction. Some ladies give a history of their nipples being inverted from childhood. However, if the nipple retraction is a new finding, then it must be looked at with suspicion. Nipple directional changes or scaling. Many of the ductal abnormalities, like papillomas, papillary carcinomas, atypia, dysplasia, DCIS or even Intraductal carcinomas can present with any of the nipple symptoms. With the help of advance technologies especially high resolution ultrasonography, MRI and DR mammograms these diagnosis can be made at and much earlier stage. Further evaluation with guided biopsies are suggested. 3. Any lump in the armpits From my experience interpreting breast MRIs and ultrasounds, lymph node evaluation is a critical component that patients rarely consider during self-examinations. I've diagnosed several cases where palpable lymph nodes were the presenting symptom, leading to the discovery of occult breast cancers that weren't detectable through conventional screening. My clinical advice: Any palpable lump in the armpits must be evaluated with ultrasonography and SOS, as well as further investigations like FNAC, biopsy, mammography, MRI, etc. Even primary breast cancers are found in the axillary tail of the breast, which is found in the armpit. Any lymph node that remains palpable for more than two weeks, especially if it's firm, fixed, or progressively enlarging, requires immediate imaging evaluation with ultrasound and possible tissue sampling. 4. Any skin discolouration over the breast In my radiological practice, inflammatory changes represent some of the most challenging cases to diagnose early. Inflammatory breast cancer, while rare, can initially present as simple skin irritation that patients often treat with topical remedies for weeks before seeking medical attention. Through my imaging experience, I've learned that skin changes that don't respond to conservative treatment within 1-2 weeks, particularly when accompanied by breast swelling or warmth, require immediate evaluation with specialised imaging protocols. I've diagnosed several cases of inflammatory breast cancer where patients initially attributed symptoms to allergic reactions or skin conditions. 5. No signs at all I can not stress enough this last point that most of the breast cancers can only be caught at an early stage with the help of screening. Screening implies the patient does not have any complaints and still gets a routine checkup, and a mammography is done. According to the recommendations by the Breast Imaging Society of India (BISI), annual screening mammograms are recommended for those between the ages of 40 and 70. In case of high-risk individuals with a family history of breast cancer or BRCA 1 or 2 genes positive amongst others, the screening starts at a much earlier age. After years of interpreting breast imaging and counselling patients, I cannot stress enough the importance of trusting your instincts about your body. In my practice, I maintain an open-door policy for patients who notice changes, no matter how minor they may seem. Also, the take-home message again is that to diagnose this disease early, we must understand the importance of screening protocols and consult our medical professionals for annual clinical breast examinations.

Your birth certificate says 45 but your heart may be 55: Study shows how Americans' hearts are ageing faster than them
Your heart may be ageing faster than your birth certificate suggests, and for many Americans, especially those with lower income or education, that age gap is alarmingly wide. According to a study published in JAMA Cardiology on July 30, 2025, the average American's cardiovascular system functions years older than their actual age, about four years older for women and seven years older for men. (Also read: Cardiologist explains how a simple blood test can predict heart attack risk years in advance: 'Before symptoms appear…' ) New 'risk age' concept highlights alarming heart health gaps among low-income adults. (Shutterstock) What is 'risk age' and why it matters The study, based on data from over 14,000 adults, introduces a new concept called 'risk age', a way of communicating heart disease risk not through percentages, but by comparing a person's heart to that of someone in perfect cardiovascular health. Study reveals that many Americans have hearts that function years older than their actual age. (Pixabay) Researchers found striking disparities based on socioeconomic status. Adults with only a high school education or less showed significantly older heart ages, up to 10 years older in some cases. Income mattered even more: lower-income men had hearts ageing more than 8 years ahead of their age, and nearly 1 in 3 had heart ages 10+ years older. Impact of education, income and race on heart ageing Non-Hispanic Black adults had the highest gaps, especially men, whose hearts aged an average of 8.5 years beyond their chronological age. Hispanic and Asian adults also showed disparities, but Asian women had the smallest gap, less than three years. Instead of saying a patient has a 15 percent risk of heart disease, doctors can now say their heart functions like someone a decade older. This 'risk age' method may help younger adults understand their health risks more clearly and encourage better prevention efforts. While individual choices matter, the research highlights how education and income levels shape heart health deeply. The findings call for not just lifestyle changes, but systemic solutions to close the cardiovascular health gap in America.
