Welcome to e health forum.

Measuring serum creatinine is a simple test and it is the most commonly used indicator of renal ‎function. More important than absolute creatinine level is the trend of serum creatinine levels over ‎time.‎

The typical human reference ranges for serum creatinine are: ‎
‎ For women 0.5 to 1.0 mg/dL (about 45-90 μmol/L) and ‎
‎ In case of men 0.7 to 1.2 mg/dL (60-110 μmol/L) for men‎.

The levels mentioned for your grandfather, indicate the possibility of chronic renal disease associated with aging or conditions like hypertensive nephropathy, diabetes, etc.

Normally, people with chronic kidney disease are recommended to have small regular meals, do ‎energy-increasing physical activities and eat a low calorie diet (food that is low in protein, sodium, ‎potassium and phosphorus counts). Some patients of CKD are advised to have less intake of fluids.‎

Mostly, we consume potassium through milk, yogurt; fruits like avocado, kiwis, oranges, papayas, ‎banana, cantaloupe; Legumes - nuts; vegetables like beans, potatoes, tomatoes, spinach and fellow ‎leafy vegetables, sweet potato and animal protein. Potassium-based salt products, winter vegetable ‎juices and squash should also be strictly avoided.‎

Higher the salt intake, higher the risk of the CKD, high blood pressure and heart disease. Hence a large ‎amount of sodium intake must be restricted. Canned food, pickles, smoked meat, some frozen foods, ‎processed cheese, packed chips, junk food and crackers must also be avoided. Develop a habit of ‎reading the labels to get to know the level of sodium in the products we are consuming. Less than 5 ‎mg sodium per serving is sufficient to stay healthy.‎

Protein:‎ The limit on protein intake is 0.75g per kilogram of one's total body weight. One must consume enough ‎protein to keep oneself healthy but not in excess. Mainly meat, fish and dairy products are the sources ‎of protein. Edibles such as eggs, beef, cheese, bran breads, nuts and vegetable also contain a high ‎amount of protein.‎

Phosphorus consumption for normal people as well as for people with CKD non-dialysis is 2.7 to 4.6 ‎mg/dL. For CKD dialysis patients the target range is 3.5 to 5.5 mg/dL. Anything more than that must be ‎reduced. Poor maintenance of phosphorus can lead to not only total kidney failure but also to bone ‎diseases and heart troubles. ‎
Dairy products, nuts and beans (the main sources of phosphorus) and drinks and beverages like cocoa, ‎cold drinks and beer must be avoided.‎

Fluids:‎ Consumption of fluids is essential for normal people but for a patient of CKD, fluid intake must be ‎watched. More than 48 fl oz (1.4 L) of fluids a day must be avoided. Some fruits like apples, orange, ‎grapes and vegetables like lettuce also contain a lot of water. So, avoid such fruits.‎


Never change any food pattern or your diet program without proper consultation with your doctor.‎ It is important to have routine medical checkups and keeping a track of the recent changes that occur.‎ Proper medication and exercise is a must.‎
Smoking and alcohol consumption must be reduced, and preferably completely avoided.‎
Lower blood sugar and cholesterol levels must be maintained and observed time to time.‎

You might consider consulting a dietician or a nephrologist for additional help regarding the management of your grandfathers condition.
I hope this helps.‎
