Nutritionist shares lab tests to identify the root cause of everyday health issues

Modern lifestyle problems such as hair loss, fatigue, poor sleep, digestive discomfort, and irregular periods are becoming increasingly common, yet most people try to fix them with quick dietary changes or supplements without ever understanding what their body is truly lacking. In a recent video, top nutritionist Dr. Ryan Fernando hinted that the real solution begins with identifying the root cause. Dr. Fernando emphasizes that targeted testing allows you to understand what your body is missing, where systems are underperforming, and which deficiencies silently drive these everyday problems. Only then can diet, lifestyle changes, or supplementation become truly effective. To make this process easier, Dr. Fernando breaks down exactly which tests one should consider for each common lifestyle problem. Here are the specific tests he recommends for the symptoms most people struggle with today.
