If you use spinach in medicinal amounts and take diabetes medications, monitor your blood sugar closely. The dose of your diabetes medications might need to be changed. Check with your healthcare provider.

Kidney disease: Spinach may cause hard crystals to form in the kidneys. These crystals won't dissolve and might make kidney disease worse.
