Chronic Kidney Disease Stage 4 means that you have about 15-29% kidney function left. When you fall below 15%, that means it is time for renal replacement therapy such as dialysis.
Some of the sympthoms you are experiencing are not uncommon for someone heading towards ESRD (end-stage renal disease) (Stage 5). Some of which include:
• easy bleeding and bruising
• headache
• fatigue and drowsy feeling (more than normal or usual for you)
• weakness
• mental symptoms such as lowered mental alertness, trouble concentrating, confusion, seizures
• nausea, vomiting, and generally less desire to eat
• thirst
• muscle cramps, muscle twitching
• nocturia (night-time urination)
• numb sensation in the extremities
• diarrhea
• itchy skin, itchy eyes
• skin colour changes (grayish complexion, sometimes yellowish-brownish tone)
• swelling and puffiness (more than you had while in advanced renal failure, and most likely in the feet and/or ankles)
• difficulty breathing (due to fluid in the lungs, anemia)
• high blood pressure
• decreased sexual interest
• changes in menstrual cycle (and difficulty getting pregnant)
• decreased urine output (however, you should be aware that some people with ESRD will continue to get rid of water as urine, but not wastes - therefore, the urine may be very clear and normal-looking, and some may have increased urine output rather than decreased).
• poor digestion (varying degrees of gastroparesis).
With your advanced disease, you need to be asking these questions to and taking advice from your physicans instead of this forum. Good luck.
