Hello! Welcome and thank you for asking on HCM! The fact that your urine color has changed may indicate an urinary tract infection. I recommend performing an urine analysis, an abdominal ultrasound and a complete blood test, coupled with inflammation tests (PCR, sedimentation rate). Regarding the dizziness, when changing body position, I would recommend you to closely monitor your blood pressure in sitting and standing up position. A head up tilt test may be necessary to exclude possible orthostatic intolerance. You should discuss with your attending physician on the above issues. Hope you will find this answer helpful! Greetings! Dr. Iliri
