Outcomes for patients who undergo weight-loss surgery may be influenced by vitamin D levels, according to a new study by researchers from Johns Hopkins Medicine.Exposure to sunlight is a key factor in vitaminD levels; ultraviolet radiation from the sun triggers vitamin D synthesis in the body. As such, people with low sun exposure often have lower vitamin D levels, which has been linked to numerous health problems.Vitamin D plays a number of important roles in the body; it helps maintain bone health, aids immune system function and supports lung and heart health, among numerous other functions.
