Your Genes, Your Health: Why Genetic Testing Is the Smartest Wellness Move You Can Make
Genetic testing is transforming preventive healthcare by revealing hidden disease risks and empowering individuals—especially women—to make informed choices
By now, we're used to thinking of our genes as the blueprint of who we are. But what if they could also serve as a map—guiding us through critical decisions about our health, long before any symptoms show up? With the rise of affordable, accessible genetic testing, that future is already here.
Take the chilling cases of sudden cardiac deaths among elite athletes or seemingly healthy young adults diagnosed with advanced cancers—often without warning or obvious risk factors. According to Dr. Ashok Gopinath, Head – Partner Development, Strand Life Sciences, such scenarios, though rare, highlight a crucial truth: 'It is quite well established that beyond advanced age and lifestyle, genes play a significant role in the onset of diseases like cancer and cardiovascular conditions."
In fact, about 10% of all cancers have a hereditary basis. 'Inherited BRCA mutations, for instance, confer a 69–72% lifetime risk for breast cancer and a 17–44% risk for ovarian cancer," adds Dr. Gopinath. That's compared to baseline population risks of just 5–12% and less than 1%, respectively. Despite this, genetic testing has traditionally been recommended reactively—after symptoms, or a strong family history, surface.
But times are changing. Thanks to newer, non-invasive screening tools and plummeting costs, genetic testing is no longer a diagnostic tool of last resort—it's emerging as a proactive strategy. Tests like Genomic Health Insights (GHI) by Strand Life Sciences now allow individuals to screen for over 280 adult-onset genetic disorders, including various cancers and heart diseases, even in the absence of symptoms. 'We truly are fortunate to live in a time where every individual is empowered to take predictive tests and proactively understand their risk," says Dr. Gopinath.
As someone who treats hundreds of women facing fertility struggles, Dr. Lekhi sees genetic testing as a revolution. 'From uncovering hidden causes of infertility and miscarriage to detecting risks for PCOS, endometriosis, or premature ovarian failure, your DNA contains vital clues," she explains. And it doesn't stop there. For patients undergoing IVF, preimplantation genetic testing (PGT) helps select the healthiest embryos, thereby increasing the chances of a successful pregnancy. Non-invasive prenatal testing (NIPT), on the other hand, offers peace of mind by detecting chromosomal abnormalities early in pregnancy.
Most importantly, genetic insights can help women take control of their reproductive futures. 'Whether it's freezing eggs at 20 or addressing inherited conditions before they compromise fertility, the possibilities are staggering," says Dr. Lekhi. 'Your genes aren't your fate—they're your map. And genetic screening? That's the compass guiding you intelligently."
As science gives us more tools to understand our biology, the message is clear: we no longer have to wait for a diagnosis to act. In the evolving landscape of personalised healthcare, knowing your genetic risk may be the most empowering move you can make—for today and for the years to come.

Five strategies to manage PCOS, avoid weight gain
For women grappling with Polycystic Ovary Syndrome (PCOS), a recurring concern is its strong link to weight gain, particularly around the abdomen. This isn't merely a cosmetic issue; it's a critical component of PCOS, often exacerbating insulin resistance and hormonal proactive lifestyle strategies, especially dietary ones, can significantly help manage PCOS and mitigate weight gain. Dietician Vidhi Chawla, founder of FISICO Diet and Aesthetic Clinic, lists five key ways to manage PCOS and avoid unwanted weight gain:advertisementPrioritise a low glycemic index (GI) diet: Insulin resistance is a hallmark of PCOS, meaning your body struggles to use insulin effectively, leading to higher blood sugar and insulin levels. High insulin can promote androgen production and fat storage. A low-GI diet, rich in complex carbohydrates like whole grains (quinoa, brown rice, millets), legumes and non-starchy vegetables, helps stabilise blood sugar, reducing insulin spikes and improving insulin sensitivity. This dietary approach is fundamental for weight management in on balanced macronutrients: While often overlooked in basic dieting, the balance of protein, fats and carbohydrates is vital for managing PCOS. Ensure each meal includes a good source of lean protein (chicken, fish, eggs, tofu, lentils, beans). Protein increases satiety, helps preserve muscle mass (which boosts metabolism) and reduces insulin response. Incorporate healthy fats from sources such as avocados, nuts, seeds and olive oil, which are crucial for hormone production and reducing inflammation, further supporting weight Embrace fibre-rich foods: Fibre is your ally in PCOS management. Found abundantly in fruits, vegetables, whole grains and legumes, fibre helps slow down sugar absorption, preventing rapid blood sugar spikes. It also promotes satiety, reducing overall calorie intake, and supports a healthy gut microbiome, which plays a role in metabolism and inflammation. Aim for a diverse range of plant-based foods to maximise fibre physical activity, strength training: Exercise is a powerful tool against insulin resistance and for weight management in PCOS. While cardio is beneficial, strength training is particularly crucial. Building muscle mass improves insulin sensitivity, as muscles are a primary site for glucose uptake. More muscle also means a higher resting metabolism, helping your body burn more calories even when at rest. Aim for a combination of consistent cardio and 2-3 sessions of strength training per on stress management, sleep: Chronic stress elevates cortisol levels, a hormone that can promote abdominal fat storage and worsen insulin resistance. Similarly, insufficient sleep disrupts hunger-regulating hormones (ghrelin and leptin), leading to increased cravings and overeating. Integrating stress-reducing practices such as yoga, meditation and deep breathing, and ensuring 7-9 hours of quality sleep nightly can significantly impact your hormonal balance and weight management PCOS-related weight gain requires a holistic approach beyond simple calorie restriction. By focusing on these five pillars, women with PCOS can empower themselves to achieve better hormonal balance, sustainable weight management and improved overall well-being.

Breast cancer can return years later: Oncologist shares how to spot early signs of relapse
Breast cancer is the most common cancer in women and like every cancer, there is a chance of breast cancer recurrence even after completion of the prescribed treatment. Hence, every woman has to undergo regular follow up as advised by the treating doctor. Can we catch breast cancer before it returns? Here's what doctors want you to know.(Image by Pexels) In an interview with HT Lifestyle, Dr Anjali Kulkarni, vice president, RWE Strategy and Analytics and oncologist at 4baseCare, shared, 'Breast cancer recurrence can happen locally i.e. within the same or other breast or regionally i.e. in the axilla or neck nodes. To detect the signs of local recurrence, women can do a routine self breast examination and check overlying skin for any changes. This helps to detect local recurrence quite early. Local recurrence can be confirmed by mammography or ultrasonography.' Going to bed too soon after eating may increase the risk of breast cancer coming back, says a study.(Shutterstock) In many cases, recurrence happens at distant organs like liver, bone, lungs, brain and abdomen. Dr Kulkarni revealed, 'For distant recurrence there can be symptoms like bone pains, jaundice, severe headache, blood in cough or loss of weight. For such advanced stages, imaging is a definitive diagnostic method for recurrence. Mainly radiology tests like PETCT, bone scan, CT, MRI or ultrasound can detect recurrence. These methods usually detect cancer recurrence when the tumour or lesion size reaches at least 7-8 mm and visible on images.' A blood test could spot breast cancer relapse months before any scan Currently, there is an advanced technique ctDNA to identify recurrence even before it appears on the radiology images. Dr Kulkarni explained, 'This is called Circulating tumor DNA (ctDNA), a type of cell-free DNA (cfDNA) released by tumour cells into the bloodstream which can be used to identify cancer recurrence.' She elaborated, 'ctDNA detection can precede clinical or radiological evidence of recurrence by several months, allowing for early intervention. ctDNA levels can be done after treatment and can even help identify patients who are at higher risk of recurrence. Changes in ctDNA levels can be used to assess the effectiveness of treatment and guide treatment decisions.' Will your breast cancer come back? New blood test can predict with 100% accuracy. Here's all you need to know (Image by Freepik) Dr Kulkarni pointed out, 'Usually after completing the prescribed treatment, women are on follow up protocol every 3 months for the first year, then every 6 months for 5 years and then once a year. Few women with advanced breast cancer, the cancer may never go away completely. These women may continue to get treatments to help keep the cancer under check.' The follow up regimen will vary depending on the stage of disease and certain tumour types like Triple negative breast cancer which is known to be aggressive. Dr Kulkarni said, 'Women with BRCA gene mutations have a higher risk of developing bilateral breast cancer. Women who are presented with the early-stage breast cancer can be monitored clinically and radiological tests can be done at 6 monthly intervals. But aggressive cancer types require close monitoring. Technologies like ctDNA will be very helpful in these women for close surveillance.'

Treating hormonal issues at birth can ensure normal growth in kids
Hormonal disorders in children can have significant physical, emotional, and social impacts. These conditions can affect growth, development, and overall well-being, making early diagnosis and treatment essential. Understanding these issues can help parents and caregivers take proactive steps to support their child's health and development, says Dr Riaz I, Professor, Paediatric and Adolescent Endocrine Clinic, Government TD Medical College, Alappuzha, in an interview with Unnikrishnan S. Edited excerpts: Q: What are the most common hormonal disorders in children? The most important endocrine disorder in children is hypothyroidism, especially congenital hypothyroidism, a condition present at birth, where the thyroid gland doesn't produce enough hormones, often due to gland maldevelopment. It's the most common preventable cause of intellectual disability. Early diagnosis and treatment at birth can ensure normal growth and brain development. Other common hormonal disorders include type-1 diabetes mellitus, acquired hypothyroidism, growth hormone deficiency, precocious puberty, delayed puberty, congenital adrenal hyperplasia, obesity & metabolic syndrome, hyperthyroidism (Graves' Disease) Q: What early signs should parents watch for? Abnormal growth patterns: It is important to record the height and weight of every child in a growth chart at periodic intervals. Slowing down or accelerated height or weight gain, falling off, or jumping across growth percentiles on a growth chart are all signs of an endocrine disease. Signs of diabetes: Frequent urination, excessive thirst, weight loss, bedwetting, or genital fungal infections. Puberty issues: Early signs (before 8 years in girls, 9 years in boys) or delayed signs (after 13 in girls, 14 in boys). Hypothyroidism: Fatigue, sleepiness, constipation, cold intolerance, jaundice, poor activity in newborns. Hyperthyroidism: Heat intolerance, sweating, unexplained weight loss, diarrhoea, irritability. Unusual hair growth or acne: Could indicate excess adrenal hormones or polycystic ovary syndrome (PCOS) in girls. Skin changes: Dark, velvety skin in folds (acanthosis nigricans) may suggest insulin resistance. Menstrual irregularities: Absent, delayed, or irregular periods in adolescents can point to hormonal imbalances. Q: Are there any preventive measures parents can take to avoid hormonal disorders in children? While not all hormonal disorders can be prevented, early detection and a healthy lifestyle play a key role. For example, congenital hypothyroidism can be silent at birth, so it is essential to check thyroid levels in all newborns. Early treatment can prevent intellectual and physical delays. Encouraging a balanced diet rich in fruits, vegetables, whole grains, and lean proteins is also important. Limiting sugar, salt, fats, and junk foods can help prevent obesity and insulin resistance, which are linked to various hormonal issues. Ensuring that children get at least an hour of physical activity or play each day is crucial for maintaining a healthy weight and supporting hormone balance. Lastly, regular paediatric checkups to monitor growth and development are important. Early identification of any deviations allows for timely treatment of potential endocrine disorders. Q: What are the current treatment options for children diagnosed with hormonal diseases? Treatment for hormonal disorders in children varies based on the condition but generally focuses on restoring normal hormone levels and supporting growth and development. Common treatments include: Type-1 diabetes: Managed with insulin therapy (injections or pump), regular blood glucose monitoring, dietary adjustments, and self-care education Hypothyroidism: Treated with oral levothyroxine (synthetic thyroid hormone), with regular thyroid function tests to adjust dosage Hyperthyroidism: Treated with antithyroid medications and beta-blockers for symptom relief. In some cases, radioiodine therapy or surgery may be needed Growth hormone deficiency: Managed with recombinant human growth hormone injections, growth tracking, and periodic IGF-1 testing Precocious puberty: Treated with GnRH analogs to delay puberty. Further evaluation for underlying causes, such as CNS lesions or adrenal disorders, is also necessary Delayed Puberty: Often requires watchful waiting for constitutional delays, but hormone therapy (testosterone or estrogen) may be used if a pathological cause is found or if puberty is significantly delayed Congenital adrenal hyperplasia: Managed with glucocorticoids and sometimes mineralocorticoids, along with salt supplementation in salt-wasting forms. Growth, puberty, and adrenal crisis prevention are closely monitored Q: How do hormonal imbalances affect children socially and emotionally? How can we support them? Hormonal imbalances can lead to low self-esteem and body image issues in children due to delayed growth, early or late puberty, weight gain, or excessive hair growth. This may cause social withdrawal, embarrassment, and bullying. To support them, it's important to address the underlying condition with prompt treatment, provide proper counselling, and create a supportive, understanding family environment.
