A study has found that vitamin D deficiency may increase the likelihood of having a Caesarean section. In the early 20th Century deformed bones in the pelvis often led to a C-section, but the problem virtually disappeared with the vitamin D fortification of milk and other foods. This background information gave way to a new study which found that women with low blood levels of vitamin D were almost four times as likely to have an emergency C-section as those with normal levels. Vitamin D has been associated with muscle weakness and high blood pressure, which helps explain the finding. Pregnant women are advised to take a thousand-unit supplement of vitamin D on top of any prenatal vitamins to avoid the risk of a C-Section. Sometimes, C-Sections can be delayed, causing birth injuries. To read the full story, click here.
