10 Best Kidney Stone Removal doctors in Istanbul

Your creatinine level is a bit above normal and your eGFR is a bit below normal. These are not a big deal and can occur due to age or some health problems in the past like angioplasty. It may not be visible in the beginning. Thus, living a healthy lifestyle such as eating well, drinking enough water, and making regular doctor visits can greatly assist your kidneys. 

It's completely understandable to have concerns about finances, but selling your kidney isn't a safe or legal way to address that. Selling organs is prohibited in most countries because it can lead to serious health complications for the donor and ethical issues. In fact, there are other ways to get financial support or assistance if needed. I recommend reaching out to local support services or financial advisors for guidance on managing your situation.
