For people with inflammatory bowel disease, following a Ramadan intermittent fasting schedule for one month does not lead to measurable changes in their quality of life or levels of depression, based...
Adults aged 30 and older with ulcerative colitis may have more severe symptoms during Ramadan fasting than younger adults with the same condition, even when accounting for differences in medication...
People with ulcerative colitis who have elevated levels of fecal calprotectin before Ramadan fasting are more likely to experience a worsening of their symptoms during the fasting period.
In people with ulcerative colitis or Crohn’s disease, fasting during Ramadan for one month does not lead to measurable changes in two biomarkers of inflammation: C-reactive protein in the blood and...
In patients with ulcerative colitis, fasting during Ramadan for 14 to 15 hours per day is linked to a small but measurable increase in disease activity symptoms, especially in individuals aged 30 or...
In one woman with ulcerative colitis, a daily 14-hour fast for two months was linked to better blood sugar control after eating (lower OGTT), even though her fasting blood sugar rose slightly, with...
In one person with ulcerative colitis, following a 10-hour eating window and 14-hour fasting period for eight weeks was linked to a small rise in hematocrit and white blood cell count, while...
A person with ulcerative colitis reported no gastrointestinal symptoms while following a 10-hour fast, 14-hour eating schedule for eight weeks, and symptoms remained controlled as long as they...
In one person with ulcerative colitis in remission, following a 10/14 intermittent fasting schedule for eight weeks did not cause harmful changes in liver function, blood fats, or thyroid hormone...
In a woman with ulcerative colitis in remission, following a 10-hour eating window and 14-hour fast for eight weeks was linked to lower levels of two inflammation markers in blood and stool, as well...
In obese adults, skipping all food and drink from sunrise to sunset for a period of time is linked to a noticeable decrease in hip size that remains even two weeks after stopping the fast, suggesting...
In obese adults, fasting from dawn to dusk is linked to weight loss and lower BMI, but these changes do not consistently align with changes in inflammation markers, meaning inflammation may change...
In obese adults, fasting from dawn to dusk is linked to a lower resting heart rate during the fast, and this change is related to lower levels of a specific inflammatory marker called interleukin-8.
In obese adults, losing belly fat during a daily fasting period from dawn to dusk is associated with lower levels of several proteins in the blood that are linked to inflammation.
In obese adults, following a 30-day fasting period from dawn to dusk was linked to lower levels of several inflammatory proteins in the blood, and some of these reductions remained detectable two...
Scientists have noticed that people who consume more iodine sometimes have a higher risk of goiter, so they suggest maximum daily iodine intake levels of 250 micrograms for children 7–10 years and...
In children aged 7–14, the size of the thyroid gland and the presence of goiter are better signs of thyroid stress caused by too much iodine over time than blood levels of thyrotropin or...
In children aged 7 to 14, elevated TSH levels are common and stay above 10% regardless of whether iodine intake is 200–300 micrograms per day or higher, indicating that TSH levels alone cannot...
In children aged 7 to 14, higher iodine intake is associated with a predictable rise in thyroglobulin levels, but the proportion of children with very high thyroglobulin levels stays above 3%...
In Chinese children between 7 and 14 years old, consuming iodine at levels of 250–399 micrograms per day is linked to a higher likelihood of developing an enlarged thyroid gland, with higher intake...
When the adrenal glands — which produce the stress hormone corticosterone — are removed from male mice, they no longer show anxiety behaviors after being exposed to a brief social stress, proving...
When male mice experience a short, intense social stress, specific genes and inflammatory molecules become active across key stress-response organs—hypothalamus, pituitary, and adrenal gland—but this...
In male mice, prolonged social stress reduces the production of the stress hormone corticosterone in the adrenal gland by decreasing the activity of specific enzymes involved in its synthesis,...
In male mice, prolonged social stress is linked to lower levels of GABA and higher levels of glutamate in a brain region called the hypothalamus, which may disrupt normal brain signaling and lead to...
