Ckd stage 4, diabetes, creatinine 3. 44.

My mom has uncontrolled diabetes since 20yrs on insulin. Detected with CKD 4 stage doc said less than 1ltr water n has given 'no protein diet'. She takes alfakit, orofer xt, soda tabs, heart related meds, dytor etc. Is there anyway to lower creatinine her egfr was 21.9 something few months back. She also takes meds for spinal/back issue like omez n ultracet. Ecoli infection doesn't go keeps returning n she needs to keep having various antibiotics. When she eats food water drops out of her nose.. Could it be due to edema? Lungs have water (pleural effusion something) She also has hypothyroidism having thyroxine. Can't read as eyes have poor vision. She's fed up of meds and poor quality of life. Any alternate solution? Can homeopathy help alongwith current meds? Tried ayurveda didnt help. Life has become a pain for us.
