Breaking down stress: Seven ways stress impacts our bodies

Stress is linked to any number of gastrointestinal disorders, from diarrhea to irritable bowel syndrome. That’s why gastroenterologist Gregory Sayuk, MD, assistant professor of medicine and of psychiatry at Washington University School of Medicine in St. Louis, encourages his patients to relax and make time for activities they enjoy.

“Even though I’m a gastroenterologist, I’ve become pretty familiar with effective strategies to treat stress and anxiety because they are inseparable in a lot of individuals,” Sayuk says.

“I can give them all of the bowel-specific medications in the world, but if you don’t address stress, they’re probably never going to be satisfied with anything I give them.”

Chronic stress can cause our muscles to involuntarily contract, leading to pain in our necks, backs and jaws as well as headaches.

“That fight-or-flight response puts us in a defensive mode to the detriment of the muscle tissue,” says Jennifer Miller, PT, DPT, CLT, a physical therapist at the School of Medicine.

“The long-term consequences can be chronic pain. There is this vicious circle of stress-pain-stress-pain, which can lead to inactivity, which can impact all sorts of social interactions. And from a musculoskeletal aspect, the less we move, the less fit we are.”

Stress can inflame acne and trigger psoriasis and eczema symptoms. Our skin, after all, is our body’s No. 1 immune organ, and when it suffers, so do our complexions.

“When a patient is less stressed, you will often see their condition improve,” says dermatologist Eva Hurst, MD, assistant professor of medicine. “Taking the time to relax to focus on the mind and body is important for a lot of these diseases.”

Although more research is needed, there is a link between stress and cardiovascular disease, says cardiologist Andy M. Kates, MD, associate professor of medicine. He says studies show that workers who experience high levels of job stress have an increased risk of cardiovascular disease. Some victims of chronic stress compound that risk by smoking, drinking and eating unhealthy foods.

Acute stress, such as the stress we experience when a loved one dies or after a natural disaster such as an earthquake, also can lead to stress-induced cardiomyopathy, a reversible heart condition. It’s rare, but well-documented, Kates says.

“It’s also known as tako-tsubo, a Japanese term for octopus urn,” Kates says. “The heart ends up looking like an octopus and balloons out.”

Kates encourages his at-risk patients to develop healthy coping mechanisms.

“The question is what can be done about it,” says Kates. “The best thing to do is prevention — tobacco cessation, treating high blood pressure, maintaining a healthy weight. But also educating yourself about the effects of anxiety and anger.”

The stress reaction can spike glucose levels and lead to poor eating choices, says

Garry Tobin, MD, associate professor of medicine and director of the Washington University School of Medicine Diabetes Center. And there is some evidence that stress even can lead to diabetes.

“Can stress cause diabetes? The answer is maybe. Can stress lead to changes in your blood sugar? The answer is absolutely,” Tobin says.

Tobin says patients who control their stress tend to do a better job managing their diabetes.

Stress can prevent the brain from switching offline, making sleep elusive. Kelvin Yamada, MD, director of the Washington University Sleep Medicine Center, says a period of winding down before sleep can help.

“Anytime you activate your brain, whether through stress, exercise or studying, it’s harder to fall asleep at bedtime,” Yamada says.

“Telling someone to relax is easier said than done, but developing good sleep habits and coping mechanisms for stress are better alternatives than medications.”

Yamada adds that college students who work into the night and sleep late develop “delayed sleep phase.” Staring at a bright computer monitor late at night further exacerbates the condition.

“During finals, college students are going to stay up late studying, reinforcing delayed sleep phase,” says Yamada says.

“The problem is some may have a hard time resuming a normal sleep cycle. It makes getting to that 9 a.m. class very difficult.”
