Constipation Could Raise Heart Attack And Stroke Risks, Especially In Those With High Blood Pressure: Study

A recent study suggests that constipation may significantly elevate the risk of heart attacks, strokes, and other cardiovascular issues, especially for people with high blood pressure. According to research published in the American Journal of Physiology-Heart and Circulatory Physiology, people who experience constipation face up to twice the risk of major cardiovascular events compared to those with regular bowel movements. For example, constipated individuals are 2.7 times more likely to develop heart failure, 2.4 times more likely to experience a stroke, and 1.6 times more likely to have a heart attack or suffer from chest pain.

The research team, led by Dr. Tenghao Zheng, a clinical data analyst at St. Vincent’s Hospital in Melbourne, Australia, emphasizes that these findings could pave the way for new therapeutic approaches. By identifying constipation as a possible cardiovascular risk factor, scientists may develop targeted treatments and personalized care strategies aligned with precision medicine.

The study analyzed data from over 400,000 participants in the U.K. Biobank, a comprehensive health resource containing electronic health records, lifestyle data, and self-reported health conditions. Previous studies have linked constipation to high blood pressure and an elevated risk of cardiovascular disease. However, this study is the first to demonstrate an association between constipation and life-threatening heart health events, particularly among individuals with preexisting high blood pressure.

For participants with both constipation and high blood pressure, the risk of a major cardiovascular episode increased by 68 per cent compared to those with high blood pressure alone. Interestingly, the researchers found that constipation and heart disease share between 21 per cent and 27 per cent of genetic variants, suggesting a genetic link between the two conditions despite constipation being inherited only about 4 per cent of the time. This genetic connection may provide further insights into how gastrointestinal health impacts the cardiovascular system, warranting more investigation into the underlying mechanisms.

While researchers continue to explore the connections between digestive health and heart disease, there are several steps people can take to ease constipation, potentially reducing associated health risks:

A diet rich in fibre is essential for regular bowel movements. Fruits, vegetables, whole grains, and legumes are excellent fibre sources that help soften stool and promote regularity. Aim for at least 25-30 grams of fibre daily, gradually increasing intake if you're consuming less.

Dehydration is a common cause of constipation, as water is necessary for stool to pass smoothly through the digestive tract. Drink plenty of water throughout the day to keep your digestive system well-hydrated and promote smoother bowel movements.

Physical activity stimulates the muscles in your intestines, which can help improve bowel regularity. Aim for at least 30 minutes of moderate exercise most days of the week, as this can help reduce constipation and support overall cardiovascular health.

Establishing a daily routine for bathroom breaks can help regulate bowel movements. If possible, schedule time in the morning or after meals to allow your body to develop a consistent rhythm, which can ease constipation.

Probiotics can improve gut health by fostering beneficial bacteria that aid digestion. Yogurt, kefir, sauerkraut, and probiotic supplements may help balance your gut microbiome, reducing constipation symptoms over time.
