# Post-Tet 2026 Health Crisis: Vietnam Braces for Surge in Diet-Related Medical Cases and Fitness Industry Boom

As Vietnam's Tet holiday period concludes in mid-February 2026, a predictable yet significant public health pattern is emerging that will shape the healthcare and wellness sectors through the coming months. Multiple medical experts and health institutions are responding to what has become an annual post-holiday health crisis, signaling broader trends that will impact Vietnamese society well into spring 2026.

The Current Situation: A Perfect Storm of Health Risks

The convergence of several factors during Tet 2026 has created conditions ripe for widespread health complications. According to Article 2, PGS.TS.BS Nguyễn Trọng Hưng from the National Institute of Nutrition identified the core problem: Vietnamese people are "loosening" their health routines during Tet due to gym closures, social obligations, and a mentality that the holiday is time to completely abandon established wellness practices. The health impacts are multifaceted. Article 1 documents widespread complaints of bloating, gas, and digestive difficulties resulting from high-protein, high-fat diets combined with reduced physical activity. More seriously, Article 4 reveals that the Ministry of Health statistics show over 80% of food poisoning cases during Tet come from familiar foods, with a recent Danang incident involving fermented fish causing Clostridium Botulinum poisoning—a potentially fatal condition affecting the nervous system. Article 5 highlights particularly vulnerable populations: people with diabetes and hypertension who either over-restrict their diets out of fear or dangerously indulge under the assumption that "a little bit won't hurt." This dual-risk behavior pattern among chronic disease patients represents a ticking time bomb for the healthcare system.

Key Trends and Signals

### 1. Preventive Medical Guidance is Accelerating The timing and coordination of medical advice across multiple healthcare institutions (National Institute of Nutrition, University of Medicine and Pharmacy Hospital HCMC, Hospital 19-8) suggests a proactive response to anticipated post-Tet health emergencies. Article 3's detailed nutritional guidelines from BS.CK2 Huỳnh Tấn Vũ about the "four essential nutrient groups" and Article 4's food safety warnings from TS Lê Thị Hương Giang indicate institutional preparation for an influx of patients. ### 2. The "Three-Legged Stool" Framework is Gaining Traction Article 2 introduces the concept of nutrition, lifestyle, and exercise as the "three-legged stool" of health—with exercise being the most neglected component during Tet. This framework is being promoted systematically, suggesting it will become a cornerstone of public health messaging in coming weeks. ### 3. At-Home Fitness Solutions are Being Positioned as the Primary Solution Both Articles 1 and 2 emphasize home-based exercise routines specifically designed for post-Tet recovery. The detailed descriptions of gentle exercises (knee-to-chest positions, seated twists, cat-cow poses) indicate preparation for a population that has become deconditioned and needs graduated re-entry into physical activity.

Predictions: What Happens Next

### Short-Term (1-2 Weeks Post-Tet): Healthcare System Strain Vietnamese hospitals and clinics will experience a significant surge in patients presenting with: - Acute digestive disorders (bloating, constipation, acid reflux) - Food poisoning cases, particularly from fermented foods and preserved meats - Cardiovascular incidents among hypertension patients - Diabetic emergencies from blood sugar spikes Emergency departments will see 20-30% higher patient volumes compared to pre-Tet baseline, with gastroenterology and internal medicine departments bearing the heaviest load. This prediction is supported by Article 4's warning that "just one small mistake can make Tet unpleasant, even requiring emergency hospitalization." ### Medium-Term (1-2 Months): Fitness and Wellness Industry Boom The post-Tet guilt cycle will trigger predictable consumer behavior. Article 2 notes that many people "frantically search for ways to lose weight" after Tet holidays. This will manifest as: - **Gym membership surge**: Fitness centers will experience their annual "Tet resolution" enrollment wave, with 40-50% increases in new memberships during late February and March - **Nutrition consultation demand spike**: The detailed nutritional guidance in Articles 3 and 5 suggests growing public awareness of professional dietary management, leading to increased bookings at nutrition centers - **Home fitness equipment sales**: Given the emphasis on at-home exercises in Articles 1 and 2, retail sales of yoga mats, resistance bands, and home exercise equipment will increase significantly ### Medium-Term (2-3 Months): Policy and Public Health Response The systematic nature of expert warnings across multiple articles suggests coordination at the Ministry of Health level. We can expect: - Launch of a national post-Tet health recovery campaign by late February 2026 - Increased food safety inspections targeting fermented and preserved foods - Public service announcements emphasizing the "three-legged stool" approach to health - Potential regulatory discussions about labeling requirements for high-risk traditional Tet foods ### Long-Term Structural Change: Gradual Health Behavior Modification The sophisticated medical guidance being provided—such as Article 5's "reverse eating" strategy for diabetics and hypertension patients (eating soup and vegetables before carbohydrates)—indicates Vietnam's healthcare system is moving toward more nuanced, sustainable health management rather than restrictive approaches. This suggests a slow but meaningful cultural shift in how Vietnamese people approach holiday eating and year-round wellness, though traditional Tet food practices will remain largely unchanged.

The Underlying Dynamic: Annual Cycle Becoming More Pronounced

What makes 2026 significant is not that these post-Tet health issues are new, but that the medical establishment's response has become more coordinated and preventive. The detailed, specific guidance across all five articles—published within a 48-hour window—suggests Vietnamese health authorities are treating post-Tet recovery as a predictable public health event requiring systematic intervention. This institutionalization of post-Tet health management indicates the problem has grown severe enough to warrant dedicated resources, and suggests similar coordinated campaigns will become standard in future years.

Conclusion: A Preventable Crisis That Will Partially Repeat

Despite extensive medical guidance, the 2026 post-Tet health impact will largely follow historical patterns. Cultural traditions around Tet eating are deeply rooted, and the social pressure to participate in festive meals overrides health concerns for most Vietnamese people. However, the sophisticated medical response framework being established in 2026 will likely reduce the severity of outcomes over time, creating a gradual improvement trajectory rather than immediate transformation. The key question is whether this preventive health infrastructure can scale quickly enough to match Vietnam's rapidly growing middle class, whose increased purchasing power enables more excessive Tet celebrations—and consequently, more severe health impacts.
