Physician warns frequent energy drink use can conceal underlying health problems

Regular reliance on energy drinks to sustain alertness may indicate more than a habit, a UK family physician has cautioned. Dr. Sermed Mezher says these beverages do not truly supply energy; rather, they interfere with the body's signals for rest and can foster a repetitive dependence.

Dr. Mezher explained the biological mechanism: common stimulants in energy drinks inhibit adenosine, a brain chemical that accumulates to trigger sleepiness. By suppressing that signal, the brain perceives wakefulness even though the body still requires recovery.

According to the doctor, many consumers reach for these products to cope with issues they have not identified. Persistent tiredness can stem from insufficient sleep, chronic stress, anxiety, undiagnosed attention-deficit disorders or nutrient shortfalls such as deficiencies in vitamin D or B12.

The physician warned that daily consumption can evolve into tolerance and dependence. Over time, the body adapts to the stimulant effect, prompting increased intake to achieve the same alertness and perpetuating a cycle of fatigue and temporary stimulation.

That pattern, Dr. Mezher noted, carries immediate and longer-term health implications. Short-term effects reported include elevated heart rate, raised blood pressure, mood disturbance and disrupted sleep; prolonged misuse may heighten risks for cardiovascular and sleep-related disorders, potentially worsening baseline fatigue.

He advised anyone experiencing persistent exhaustion to avoid habitual use of energy drinks and instead investigate root causes. Recommended steps include prioritising restorative sleep, stress management, dietary improvement and medical assessment — including tests for vitamin levels and mental health evaluation when indicated.

Health authorities observe rising consumption of these beverages, particularly among students and professionals with extended working hours. Clinicians emphasise that stimulants offer only transient alertness and cannot substitute for adequate rest, nutrition and healthy lifestyle measures.
