What is the function of kidneys? - #12468
I am really worried about my health these days. I’ve been having some weird symptoms like back pain and swelling in my legs. It all started a few weeks ago, and honestly, I didn’t pay much attention to it at first. But then a friend mentioned it might be related to kidney issues, and I felt this sudden panic. I never thought about the kidneys much before this. I mean, What is the function of kidneys anyway? I did some quick searches, and it seems like they play a huge role in filtering waste, balancing electrolytes and all that good stuff. But can someone explain it more simply? What is the function of kidneys in a way that a layperson like me can really grasp? Are there signs I should really look out for that indicate my kidneys might be struggling? I’m scheduled for some tests soon, but I can’t help but think, What is the function of kidneys in relation to the issues I’ve been having? Should I be worried? I just want to make sure I'm not missing anything important. Any insights would be super helpful! Thanks!

Doctors’ responses
Kidneys are actually fascinating organs with several crucial functions. Primarily, they act as the body’s natural filtration system, expelling waste products from the blood and excess water in the form of urine. In doing so, they maintain the body’s fluid and electrolyte balance, adjusting levels of sodium, potassium and other important minerals necessary for proper body function. They also play a role in regulating blood pressure by controlling fluid volume and the release of hormones like renin which contributes to blood pressure regulation. Additionally, kidneys activate vitamin D, crucial for healthy bones, and produce erythropoietin, a hormone that stimulates the production of red blood cells. Now, in terms of symptoms like back pain and leg swelling, these can potentially be related to kidney problems, especially if they’re accompanied by things like changes in urination, fatigue, or blood in urine. Swelling can occur because kidneys aren’t removing excess fluid effectively, leading to its accumulation in your tissues. However, these symptoms can also be related to other conditions, so it’s important not to jump to conclusions. Keep an eye out for persistent or worsening symptoms, and it’s good that you have tests scheduled soon. Kidney function tests like blood creatinine levels, blood urea nitrogen (BUN), and urine tests could provide more clarity on how well your kidneys are functioning. Remember, issues like these can be multifactorial so factors like lifestyle, diet, and comorbid conditions also matter. Absolutely follow up with your healthcare provider who can interpret your test results within the context of your overall health status.
