Why kidney swelling happens? - #12396

Advait

I am really worried about my dad, he’s been having this kidney swelling for a while now. At first, he just complained about some discomfort in his lower back, but then we noticed his stomach area looked kinda puffy, like he’s gained weight overnight! He went to the doctor and had some tests done, and they mentioned it might be related to his kidneys. It’s been a bit scary not knowing exactly why kidney swelling happens. Can it be like a buildup of fluid or something more serious? He also has high blood pressure, which the doctors say could be related too. But I’m confused - does that mean we should expect more kidney swelling because of his blood pressure issues? I just can't wrap my head around why kidney swelling happens in the first place. Is there like a common reason for this, or could it be a bunch of different things? I feel bad asking, but I hope its not something life-threatening. Just trying to make sense of why kidney swelling happens, and what we should be doing next. Any advice or insights would be super helpful, thanks!

Kidney swelling, or hydronephrosis, happens when there is a blockage or obstruction that prevents urine from draining adequately from the kidney to the bladder. This blockage can lead it to build up, causing the kidney to swell. There are several potential causes for kidney swelling. Kidney stones, which can obstruct urine flow, are quite common. Infections in the urinary tract like pyelonephritis can also be a factor, leading to inflammation and swelling. It might be due to an enlarged prostate in men, tumors, or strictures in the urinary tract. Since you mentioned your dad has high blood pressure, it’s worth noting that chronic high blood pressure can damage kidneys over time, potentially leading to kidney diseases where swelling might manifest as a secondary symptom. High blood pressure can sometimes be both a cause and consequence of kidney problems. It’s critical to manage blood pressure effectively to prevent further damage. If kidney swelling is persistent or associated with symptoms like severe pain, fever, or blood in the urine, it’s imperative to have timely medical evaluation and intervention. What’s essential right now is following your doctor’s advice closely. They might suggest additional imaging studies like an ultrasound or CT scan to determine the underlying cause, and possibly a urologist or nephrologist referral. Treatments can vary depending on the cause — from antibiotics for infections to possible procedures to remove obstructions like stones. Ensure your dad maintains a healthy lifestyle, managing his blood pressure with appropriate medication, dietary adjustments, and regular follow-ups with his healthcare provider. In any case, if his symptoms worsen or if new symptoms arise, he should seek immediate medical attention to avoid complications.
