Beets and kidney stones: what to know

Beets contain oxalate, a natural substance found in many foods. In some people, oxalate can join with calcium in urine and contribute to calcium oxalate crystals. This does not mean that eating beets causes every kidney stone, and food advice depends on your stone analysis, urine results, and overall diet.

Fluids help dilute urine, while a varied diet supplies calcium that can bind oxalate in the gut. Avoid making a major restriction based on one food without knowing your stone type. Kidney stones may cause flank or abdominal pain, painful urination, or difficulty passing urine.

Drink fluids regularly unless a clinician has prescribed a fluid limit, and keep meals balanced rather than removing vegetables on your own. If beets repeatedly coincide with stone symptoms, record the food, timing, pain, urine changes, and other drinks or foods. Bring that record to a GP consultation.

If you have had a stone, ask whether it was analysed and whether a urine assessment could guide prevention. An abdominal ultrasound may help assess the urinary tract when a clinician thinks imaging is appropriate.

Arrange prompt medical assessment for new severe flank or abdominal pain, painful urination, or difficulty passing urine. Seek urgent care if pain is accompanied by fever, chills, vomiting, marked weakness, or an inability to keep fluids down, because a blocked or infected urinary tract needs timely attention.

Ask: What type of stone did I have? Do I need a urine test or imaging? Should I limit beets, and what serving pattern is reasonable for me? How much fluid is suitable with my medical history?
