“Our body is a single system in which all elements are interconnected. When an organ malfunctions, it reverberates throughout the system,” says cardiologist Suzanne Steinbaum, MD, chief physician of the Women’s Health Unit at Lenox Hill Hospital in New York. For example: in diabetes, excess sugar and insulin in the body causes inflammation, which destroys the arteries, allowing plaque to form. This process increases the risk of heart attacks and strokes. Thus, being initially a blood sugar problem, diabetes can lead to heart disease. Celiac disease + thyroid disorders Approximately one in 2008 people in the world suffers from celiac disease, an autoimmune disease in which the consumption of gluten leads to damage to the small intestine. According to a study conducted in 4, patients diagnosed with celiac disease are three times more likely to develop hyperthyroidism, and four times more likely to be hypothyroid. Italian scientists who have studied this relationship of diseases suggest that undiagnosed celiac disease triggers a cascade of other body disorders. Psoriasis + psoriatic arthritis According to the National Psoriasis Foundation, one in five people with psoriasis develop psoriatic arthritis—that’s 7,5 million Americans, or 2,2% of the population. Psoriatic arthritis causes inflammation of the joints, making them stiff and painful. According to experts, about 50% of cases remain undiagnosed in time. If you have psoriasis, it is recommended to pay attention to the health of the joints as well. Pneumonia + cardiovascular disease According to a study by the American Medical Association in January 2015, people who have had pneumonia have an increased risk of heart attack and stroke in the next 10 years after suffering the disease. Although the relationship between the two diseases has been found before, this study for the first time looked at specific people with pneumonia who did not have signs of cardiovascular disorders before the disease.
