Weakened Immune System
Individuals who have insufficient levels of vitamin D are more susceptible to upper respiratory infections such as sinus infections and colds, as well as lower respiratory infections like bronchitis and pneumonia. On the contrary, those who have adequate levels of vitamin D experience fewer complications during hospital stays and after surgeries. Maintaining vitamin D levels at or above recommended levels is associated with improved immune function and reduced respiratory inflammation. By reducing inflammation, the incidence of infections and occurrences of asthma can be decreased.
How Chronic Kidney Disease Affects Vitamin D Levels
Chronic kidney disease can lead to a deficiency in vitamin D, rather than being caused by it. In certain kidney diseases, the body’s ability to produce vitamin D and convert dietary vitamin D into its active form is hindered. This conversion process is crucial for overall health because, even if sufficient amounts of vitamin D are consumed, without its active form, the body cannot effectively utilize it. The active form of vitamin D plays a vital role in delivering calcium and other essential minerals to the bones.
Although there may be an ample supply of vitamin D and calcium in the body, without proper kidney function, these nutrients cannot be utilized. As a result, the body experiences a calcium deficiency, triggering a parathyroid reaction. This process initiates the breakdown of bones to release calcium.
If you are in the early stages of kidney disease, it is important to monitor your vitamin D levels carefully, especially if dialysis is being considered as a treatment option.
