A review of the year’s most prominent searches reveals a pattern of concern surrounding both emerging and persistent health challenges.
The top search query of the year centered on differentiating between the symptoms of influenza, COVID-19, and dengue fever. Many individuals are increasingly turning to online resources to quickly assess whether symptoms like fever, cough, body aches, or rashes warrant medical attention.
“People’s confusion and fear of concurrent diseases are increasing,” one analyst noted, “as we see the emergence of disease outbreak hotspots and a rise in seasonal infections.” Users actively sought facts on “flu symptoms” and related infections, demonstrating continued concern about respiratory viruses and mosquito-borne illnesses.

Heart Health Takes Center Stage
A growing number of searches focused on proactive heart health, specifically, “What specific steps can I take to lower my blood pressure readings and cholesterol levels?” This surge reflects a heightened awareness of blood pressure and cholesterol as critical indicators of heart disease risk.

Research indicates a rising prevalence of heart and metabolic problems – including blood pressure, cholesterol, and A1C levels – across various geographic regions. While aware of the long-term risks of heart attacks and strokes, many struggle to fully understand the impact of daily habits like diet, exercise, stress, and sleep.
The Global Diabetes Epidemic
diabetes emerged as the most common health inquiry worldwide, with searches like “How can I lower my A1C and control diabetes?” dominating online searches. Specific questions included “How do I lower my HbA1c level?”, “What is the optimal blood sugar level?”, and “Can prediabetes be treated?”

The Persistent Puzzle of Fatigue
“Why do I feel tired all the time?” became a widespread query, spanning all age groups. Individuals are considering a range of potential causes, including anemia, thyroid problems, vitamin deficiencies, and lingering COVID-19 symptoms. The impact of stress, sleep quality, and excessive screen time are also top of mind.
Research on health search patterns for 2025 highlighted growing interest in chronic fatigue and persistent cognitive symptoms following COVID-19 infection.The complexity of fatigue – stemming from multiple potential causes – often leads to confusion among those attempting self-diagnosis.
The Shadow of Cancer
Perhaps the most emotionally charged search trend involved questions about cancer: “Do I have cancer?” Searches focused on symptoms like headaches, chest pain, lumps, unexplained weight loss, and changes in bowel movements.
The continued public concern about cancer, a disease that profoundly impacts families and often carries a fatal prognosis, is undeniable. People are increasingly turning to search engines as a first step in evaluating their symptoms, before deciding whether to seek emergency medical help.
