Persistent fatigue, unexplained weight gain and declining sperm health are increasingly being reported by relatively young patients. While these symptoms are often treated as separate medical issues, endocrinologists now believe they share a common underlying cause:chronic low-grade inflammation.
In an interview with this correspondent, Dr Hetashvi Gondaliya, specialist in Diabetes and Endocrinology at CK Birla Hospitals, Jaipur, explains that silent inflammation is quietly disrupting hormonal balance, metabolism and reproductive health—often without obvious warning signs.
“Constant fatigue, unexplained weight gain and declining sperm health are often treated as unrelated complaints, but chronic low-grade inflammation is the common link connecting them,” says Dr Gondaliya. She adds that many patients receive fragmented treatment, while the underlying inflammatory process continues unchecked.
Unlike acute inflammation caused by infections or injuries, low-grade inflammation develops slowly over years. It quietly interferes with the body’s regulatory systems, reducing resilience and increasing the risk of long-term metabolic and hormonal disorders.
Hormonal imbalance under inflammatory stressAccording to Dr Gondaliya, persistent inflammation directly disrupts hormone function. “It increases cortisol levels and impairs the action of insulin and testosterone, leading to increased fat storage,” she explains.
This hormonal disturbance slows metabolism, promotes abdominal obesity and worsens insulin resistance. In men, reduced testosterone levels further contribute to fatigue, low energy, mood changes and reproductive decline, creating a vicious metabolic cycle.
Impact on sperm health and fertilityThe effects of chronic inflammation extend beyond weight gain and exhaustion. “Oxidative stress damages sperm cells, reducing their count, motility and DNA quality,” Dr Gondaliya says.
From an endocrine perspective, this explains why many men with obesity or metabolic syndrome also present with subfertility. The damage often occurs gradually and remains unnoticed until fertility testing reveals compromised sperm parameters.
Lifestyle factors driving silent inflammationDr Gondaliya highlights several everyday habits that fuel chronic inflammation. “Sedentary lifestyle, poor sleep, excessive intake of ultra-processed foods, smoking, alcohol consumption and chronic stress quietly worsen this inflammatory state,” she says.
Urban lifestyles, long working hours and reduced physical activity have normalised these risk factors, making inflammation a widespread but under-recognised public health concern.
Reversible damage with timely actionDespite the alarming trends, Dr Gondaliya emphasises that chronic inflammation isnot irreversible. “The good news is that inflammation can be reversed,” she says.
Regular exercise, weight reduction, balanced nutrition rich in fruits, vegetables and healthy fats, adequate sleep, stress management and treatment of underlying conditions such as obesity, insulin resistance or thyroid disorders can significantly improve energy levels, metabolic health and reproductive outcomes.
“Rather than masking symptoms, addressing inflammation helps restore the body’s natural balance,” she concludes, offering long-term benefits across multiple systems.
