Everything you have asked
about gut health, PCOS
and weight loss.

Dt. Hashika Vyas is a certified dietitian with a degree in Holistic Science in Health, Nutrition and Dietetics. She has 6+ years of clinical experience specialising in gut health, IBS, PCOS, hormonal nutrition and weight loss, with additional training in clinical Ayurvedic nutrition.

Yes. Dt. Hashika Vyas had IBS-D and recovered using the same three-phase method she now uses with every gut health client. This personal recovery directly shaped her root-cause approach to nutrition rather than generic dietary advice.

Dt. Hashika Vyas has worked with 1000+ clients across 15+ countries, including India, the UK, the US and Europe, specialising in gut health, IBS, PCOS and root-cause weight loss.

Dt. Hashika Vyas builds a fresh, personalised Indian diet plan every single week rather than reusing a generic template. She integrates clinical Ayurveda, treats the gut-hormone-metabolism connection as one system, and addresses the psychological and mindset factors behind eating behaviour, not just food intake.

Dt. Hashika Vyas specialises in three core areas: gut health (IBS, SIBO, bloating, post-antibiotic recovery), PCOS/PCOD and hormonal imbalance, and root-cause weight loss. Within these, she also supports related concerns such as acidity, hormonal acne, irregular cycles and fertility nutrition.

Dt. Hashika Vyas is based in Mumbai, India, and operates as an online-only practice. All consultations are conducted via Google Meet, Zoom or WhatsApp video call, allowing clients across India and internationally to work with her without visiting in person.

IBS symptoms can be substantially resolved and managed long-term through a root-cause approach that addresses gut bacteria, food triggers, nervous system regulation and underlying inflammation. Most clients achieve significant, lasting symptom relief within 3 to 4 months, though IBS requires ongoing awareness of personal triggers rather than a single permanent fix.

IBS is a functional gastrointestinal disorder, meaning it does not show structural damage on standard tests like colonoscopies or blood panels. A clear test result does not rule out IBS — it confirms the issue is functional rather than structural, which is exactly where targeted dietary and gut-focused intervention helps most.

Common IBS triggers include high-fat fried foods, excess caffeine, carbonated drinks, artificial sweeteners and certain high-FODMAP foods such as onion, garlic and certain legumes. However, triggers are highly individual — an elimination and reintroduction process under guidance identifies your specific triggers rather than relying on a generic restriction list.

Most gut health clients see initial improvement in bloating and bowel regularity within 2 to 3 weeks of starting a structured program. Full stabilisation, including expanding back to a complete, unrestricted Indian diet, typically takes 3 to 4 months depending on symptom severity and duration of the condition.

Yes. Antibiotics can significantly disrupt the gut microbiome by killing both harmful and beneficial bacteria, and recovery of microbial diversity can take months without targeted intervention. Symptoms like bloating, irregular bowel movements and food sensitivities following a course of antibiotics often indicate gut dysbiosis that requires structured dietary rebuilding.

IBS-D is the diarrhoea-predominant subtype, IBS-C is the constipation-predominant subtype, and IBS-M is the mixed subtype where bowel patterns alternate between both. Each subtype requires a different fibre, hydration and food-sequencing strategy, which is why a generic IBS diet plan often fails to fully resolve symptoms.

Probiotics can help, but their effectiveness depends on whether the gut environment is ready to sustain new bacteria. A gut that is inflamed, stressed or lacking fibre and rhythm often cannot integrate probiotics effectively. Addressing the foundational gut environment first — through sleep, stress reduction and food sequencing — typically improves probiotic effectiveness significantly. This is explored in detail in "Beyond the Probiotic Pill" (Vyas, 2026), a published perspective paper on integrative gut healing.

Bloating is most commonly linked to digestion, gut bacteria imbalance, food intolerances or slow gut motility, but it can also be influenced by hormonal fluctuations, particularly around the menstrual cycle, and by chronic stress affecting gut-nervous system communication.

Yes. The gut and nervous system are directly connected through the gut-brain axis, and chronic stress can directly trigger or worsen IBS symptoms including bloating, urgency and irregular bowel movements. Addressing nervous system regulation through sleep, morning routine and stress management is often a necessary first step before dietary changes can be fully effective.

SIBO (Small Intestinal Bacterial Overgrowth) occurs when bacteria that normally live in the large intestine overgrow in the small intestine, causing bloating, gas and altered bowel habits. SIBO is present in a significant proportion of IBS cases and often requires a different dietary protocol than standard IBS management, making accurate identification important.

In May 2026, a global medical consensus published in The Lancet officially renamed PCOS to PMOS (Polyendocrine Metabolic Ovarian Syndrome), reflecting that the condition affects insulin, hormones and metabolism, not just the ovaries. The rollout into clinical guidelines is planned over 3 years, so both terms are currently in use. The underlying condition, symptoms and treatment approach remain unchanged — only the name has been updated for clinical accuracy.

PCOD (Polycystic Ovarian Disease) is an ovarian condition where the ovaries release immature or partially mature eggs, which can develop into cysts; it is often reversible through lifestyle changes. PCOS (Polycystic Ovarian Syndrome) is a broader endocrine disorder affecting insulin, androgens and overall hormonal regulation, requiring a more comprehensive treatment approach. Treating them identically is a common mistake.

PCOS symptoms, including irregular cycles, hormonal acne and weight gain, can improve substantially through targeted nutrition, though PCOS as an underlying endocrine pattern is typically managed rather than fully reversed. PCOD, being an ovarian rather than systemic condition, often responds more completely to dietary and lifestyle intervention alone.

Diet directly affects insulin sensitivity, androgen levels and inflammation, all of which are central drivers of PCOS symptoms. A diet built around stable blood sugar, anti-inflammatory foods and adequate protein can measurably improve cycle regularity, skin and energy within 8 to 12 weeks for many clients.

Foods that support PCOS management include high-fibre whole grains like ragi and millets, protein at every meal, healthy fats, and PCOS-supportive ingredients such as methi seeds, spearmint tea and cinnamon, which have evidence supporting insulin and androgen regulation. Plans should be built around the menstrual cycle phase rather than as a single fixed template.

PCOS is strongly associated with insulin resistance, where cells respond less effectively to insulin, leading the body to store more fat, particularly around the abdomen. This metabolic pattern makes weight loss more difficult through calorie restriction alone and typically requires a specific insulin-focused dietary strategy.

PCOS is one of the most common causes of ovulatory infertility because it can disrupt regular ovulation. Nutritional intervention that improves insulin sensitivity and hormonal balance has been shown to support more regular ovulation, which can improve fertility outcomes alongside medical fertility treatment where needed.

Most PCOS clients see measurable improvement in symptoms such as energy, skin and cycle predictability within 3 weeks of starting a structured cycle-phase nutrition plan. Significant hormonal and cycle regularity improvements typically develop over 3 to 6 months, depending on the severity and duration of the condition.

Yes, elevated androgens associated with PCOS commonly cause hormonal acne, typically along the jawline and chin. Reducing high-glycaemic foods, balancing insulin through diet, and incorporating anti-androgenic foods can measurably reduce hormonal acne over several menstrual cycles.

Yes. Hormonal needs shift significantly across the follicular, ovulatory and luteal phases of the cycle. A cycle-phase-based nutrition plan, adjusting carbohydrate timing, protein needs and specific supportive foods, produces better symptom control than a single static weekly diet plan applied throughout the entire cycle.

Yes. Lean PCOS occurs in individuals with a normal or low body weight who still have insulin resistance, hormonal imbalance and irregular cycles. It is frequently underdiagnosed because the absence of weight gain leads many to overlook PCOS as a possibility despite clear hormonal symptoms.

Calorie counting often fails because it does not address the underlying driver of weight gain, such as hormonal imbalance, cortisol-driven stress eating, gut dysbiosis or insulin resistance. Without identifying which of these is the primary driver, calorie restriction frequently leads to short-term loss followed by regain.

The four most common root causes of stubborn weight gain are hormonal weight gain, cortisol or stress-driven weight gain, gut-driven weight gain linked to bacterial imbalance, and insulin-resistant weight gain. Each requires a distinctly different nutritional approach, which is why a single generic weight loss diet often fails to produce lasting results.

Sustainable weight loss through root-cause nutrition typically shows measurable results within 4 to 6 weeks, with most clients seeing significant, maintainable progress within 3 months. Rapid weight loss through extreme calorie restriction is generally not sustainable and often results in regain once normal eating resumes.

Yes. Chronically elevated cortisol from ongoing stress promotes fat storage, particularly around the abdomen, and can increase cravings for high-sugar, high-fat foods. Weight loss efforts can stall significantly if cortisol regulation, through sleep, stress management and nervous system support, is not addressed alongside diet.

Yes. An imbalanced gut microbiome can affect how efficiently the body extracts and stores energy from food, influence inflammation levels, and disrupt hormones that regulate hunger and satiety such as ghrelin and leptin. Addressing gut health is often a necessary component of resolving stubborn, gut-driven weight gain.

No. Rice, roti, dal, sabzi and other Indian staples can all be part of an effective, sustainable weight loss plan. The determining factors for weight loss are portion structure, meal timing, food combinations and the root cause being addressed, not the elimination of any specific traditional food group.

Weight regain after stopping a restrictive diet typically occurs because the underlying driver, such as insulin resistance, cortisol or gut imbalance, was never resolved, and because extreme restriction is not sustainable long-term. A root-cause approach focused on lasting habits rather than temporary restriction is designed specifically to prevent this regain pattern.

Yes. An underactive thyroid (hypothyroidism) slows metabolism and can cause weight gain that does not respond well to standard calorie restriction or exercise alone. Nutritional support tailored to thyroid function, alongside any required medical treatment, is typically necessary to see meaningful results in these cases.

Consultations are conducted via Google Meet, Zoom or WhatsApp video call, each lasting approximately 30 to 45 minutes. Clients receive a fresh, personalised Indian diet plan after each session, along with WhatsApp support between consultations for questions or flare-ups.

Each monthly program includes 4 consultations, occurring approximately once per week, along with a freshly built diet plan after every session and ongoing WhatsApp support between sessions for same-day guidance on flare-ups or questions.

Yes. Clients from the UK, US, Europe, the Middle East and across India all work with Dt. Hashika Vyas through the same online consultation format. Diet plans are built around Indian food regardless of location, with substitutions made for ingredient availability where necessary.

Blood reports and medical history are helpful but not mandatory to begin. If recent panels are available — such as vitamin D3, B12, iron, thyroid or fasting insulin — they help identify the root cause faster. Without them, the first consultation still gathers full clinical history to build an informed plan.

The first consultation involves a detailed discussion of symptoms, medical history, current medications, dietary habits, sleep, stress levels and any available test reports. This information is used to identify the most likely root cause and outline which program and approach best fits the individual case.

Yes. WhatsApp support is included between scheduled consultations, with same-day response prioritised for flare-ups, urgent questions or symptom changes that need immediate guidance before the next session.

Yes. Every diet plan is built individually around the client's food preferences, regional cuisine, allergies and lifestyle constraints. Plans are not templated, so adjustments for taste preference or food dislikes are incorporated from the first plan onward.

Progress is tracked through symptom check-ins at each consultation, periodic review of relevant health markers when available, and direct client feedback on energy, digestion, cycle regularity or weight depending on the program. Plans are adjusted weekly based on this ongoing feedback.

Programs start from Rs. 4,000 per month. This includes 4 consultations, 4 freshly built Indian diet plans, and WhatsApp support between sessions. Exact pricing depends on the specific program and is discussed during the first consultation.

Yes, a free 15-minute introductory consultation is available to discuss symptoms, history and determine which program is the right fit before any payment or commitment is required.

Consultations can be booked directly through the Book a Consultation page on the website, or by messaging directly on WhatsApp at +91 9619905898 to schedule a convenient time.

Programs are billed monthly, and most conditions require 3 to 6 months for significant, lasting results depending on severity. There is no extended contractual lock-in beyond the monthly billing cycle.

Payment details, including accepted methods, are shared directly during or after the first consultation based on the client's location and preferred payment option.

Yes. Since many conditions overlap, such as PCOS with weight gain or gut issues with hormonal imbalance, the program focus can be adjusted as priorities shift during ongoing consultations without needing to restart elsewhere.
