Chronic Inflammation: The Silent Threat Behind Multiple Serious Conditions

8/26/2026

Health experts encourage simple lifestyle changes that can help reduce inflammation and lower the risk of heart disease, diabetes, cancer and dementia.

We’ve all experienced inflammation. A cut finger becomes red and swollen. An ankle gets sore after an injury. You may develop a fever while your body fights an infection.

That kind of acute inflammation is a good thing. It’s the body’s natural defense system at work, helping us heal and recover.

The concern is when that response doesn’t switch off.

Chronic inflammation occurs when the immune system remains activated for months or even years, potentially damaging healthy tissues and organs over time. It has been linked to a number of serious health conditions, including heart disease, type 2 diabetes, certain cancers, arthritis and neurodegenerative diseases such as Alzheimer’s disease.

“Inflammation is one of the body’s most important defense mechanisms,” said Dr. Arun Jain, an internal medicine physician with DeTar Medical Group. “When you cut your finger or develop an infection, inflammation is what helps your body heal. The concern isn’t inflammation itself – it’s when the immune system stays activated after the original threat is gone.”

It May Not Be Obvious

One of the challenges with chronic inflammation is that it often doesn’t come with a clear warning sign.

Instead, people may notice they’re more tired than usual, have persistent muscle or joint aches, experience digestive problems or skin issues, or simply feel like they’re not quite themselves. Recurring infections can also be a concern.

“Chronic inflammation doesn’t announce itself with dramatic symptoms,” Dr. Jain said. “People may simply notice they’re more tired than usual, their joints ache or they just don’t feel like themselves. Those symptoms are common and can have many causes, but they shouldn’t be ignored.”

For many people, persistent fatigue may be one of the first clues that something isn’t right.

That doesn’t mean fatigue automatically signals chronic inflammation. But if you’ve been feeling unusually tired for an extended period, it’s worth talking with your primary care provider rather than simply chalking it up to getting older, being busy or having a stressful week.

Everyday Habits Can Make a Difference

There isn’t always one single cause of chronic inflammation. A number of factors can play a role, including obesity, poor nutrition, physical inactivity, chronic stress, inadequate sleep, smoking, excessive alcohol use, autoimmune disorders and persistent infections.

The encouraging news: many of the lifestyle factors associated with inflammation can be changed.

And those changes don’t require a complete overhaul of your life.

“Many of the same habits we recommend to prevent heart disease, diabetes and other chronic illnesses also help reduce inflammation,” Dr. Jain said.

That means focusing on the basics:

• Choose more whole, minimally processed foods.
• Make physical activity part of your regular routine.
• Get adequate, consistent sleep.
• Find healthy ways to manage stress.
• Maintain a healthy weight.
• Avoid smoking and limit excessive alcohol consumption.

For South Texans, that can be as simple as swapping out some highly processed foods for fresh produce, beans and whole grains; choosing grilled fish instead of fried foods; taking a walk around the neighborhood in the evening; or making time for sleep instead of treating it as optional.

The goal isn’t perfection. It’s making healthier choices consistently.

“These aren’t quick fixes, but rather long-term investments in your overall health,” Dr. Jain said.

What You Eat Matters

Nutrition is one area where even small, sustainable changes can have a meaningful impact.

An anti-inflammatory eating pattern emphasizes fruits and vegetables, whole grains, legumes, healthy fats such as olive oil, and omega-3-rich fish. At the same time, it encourages cutting back on ultra-processed foods and added sugars.

The benefit goes well beyond inflammation. These same choices can support heart health, healthy blood sugar levels and brain health.

In fact, emerging research suggests that an eating pattern lower in inflammatory potential may also benefit the brain. A recent study published in JAMA Network Open found that older adults who consumed less inflammatory diets had a significantly lower risk of developing dementia, including people with biological markers associated with increased risk.

Start With One Change

The idea of changing your lifestyle can feel overwhelming, especially when you’re juggling work, family, responsibilities and everything else that comes with life in South Texas.

You don’t have to change everything at once.

Start with one habit you can realistically maintain. Take a short walk after dinner. Add another serving of vegetables to your plate. Replace a sugary drink with water. Establish a more consistent bedtime. Then build from there.

Over time, those small choices can add up.

If you’re experiencing persistent fatigue, unexplained pain or other symptoms that concern you, talk with your primary care provider. A conversation with your doctor can help determine whether further evaluation is needed and identify steps you can take to protect your health for years to come.
