Prospective carbohydrate metabolism studies in women using a low-estrogen oral contraceptive for one year

Three-hour oral glucose tolerance tests were done before and after one year of use of a low-estrogen-type oral contraceptive (OC) in 14 women. The drug contained 0.035 mg ethinyl estradiol and 0.4 mg norethindrone. Both blood glucose and plasma insulin were measured. During the year there were no significant changes in the subjects' weights, whereas their blood pressures decreased. The results showed a significance decrease in the fasting blood glucose level after one year for women with a "normal" control test while the remainder of the values remained unchanged. For women with a "borderline" abnormal control test there was a significant decrease in the two-hour glucose level. There were no significant changes in the plasma insulin levels. These results confirm that this low-estrogen-type oral contraceptive produces minimal changes in the carbohydrate metabolism of users.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
