@iamjutta1 Welcome to Mayo Clinic Connect! Good for you for wanting to take an active approach to dealing with that recent diagnosis of CKD Stage 3b.

There are several discussions threads already in this kidney disease support group, that you can wander through and see how other members are handling their day-to-day lives. First and foremost, I would recommend you find out about and learn about what might be contributing to your CKD. Untreated diabetes or high blood pressure? Those need to be addressed to minimize further damage to your kidneys. Side effects of other medications? What can your medical team do to change meds and achieve the same desired outcome? As for what you can do, almost all of us with CKD say diet plays a critical part, and something we can control ourselves. Stop NSAIDs like Alleve and aspirin, resorting only to acetaminophen [like Tylenol] to lessen stress and damage to your kidneys. Research good food plans for you that minimize sodium, red meat, calcium, phosphorous, potassium, sugar. Many of us have additional dietary restrictions due to other health/cultural concerns, and must craft a diet that is best for us. Get good rest, and do moderate exercise, mindful of stress.

That said, it is not impossible. But will take work on your part. I have no doubt you will find a sense of accomplishment as you take on this challenge! Please tell me more about you, if you'd like.
