• Chest pain

• Muscle cramps

• Vomiting

• Fatigue

• Changes in urination frequency and appearance

• High blood pressure

• Swelling or fluid retention

If you consume too much protein in your diet, and/or consume a lot of cooked meat, this can cause high levels creatinine in the blood.

Cause #2: Intense exercise

If you have kidney damage, this could create high creatinine levels in the blood. If that’s the case, the solution would be to support your kidneys.

Cause #6: Gallbladder/liver problems

The gallbladder is very important for your digestive system. If none of the above causes relate to your condition, it could come from the gallbladder.
