Combining Holistic Health, Wellness-based Practices and Technology, VELL Health provides treatments for pervasive ailments such as chronic pain, anxiety, stress, depression, hormonal and reproductive issues, hypertension, diabetes, obesity, autoimmune diseases and many others. Becoming a Whole and Balanced You: As we care for the whole person by focusing on their physical, mental, and social needs, we understand that each of these aspects affects overall health in many different ways. That’s why following a holistic approach to wellness is the key to unlocking your potential in achieving optimal health. Stress, for example, is a psychological response to mental or emotional pressure which can also manifest in a variety of physical symptoms: headaches, eating disorders, trouble sleeping, and chronic muscle pain to name a few. If left untreated, stress can lead to more serious health conditions such as heart disease, diabetes, and obesity. There is ample scientific evidence that cultivating healthy relationships, making time for physical exercise and spiritual practices, or simply devoting time to doing the things that bring you joy, can significantly reduce stress and associated health risks. The Journey Starts Now The holistic approach to health is not a quick fix, but rather a lifelong journey of making positive choices that will lead to a healthier and happier you and it all starts with taking that first step. VELL is the world’s first holistic health platform that combines the best practices of Eastern medicine and the latest technological advancements of today 's society. VELL Health includes treatment programs for many common ailments, such as Back Pain , Constipation, Chronic Obstructive Pulmonary Disease (COPD), Depression, Erectile Dysfunction, Female Infertility, Fibromyalgia, Headache, Heart Disease, Hypertension, Irritable Bowel Syndrome (IBS), Insomnia, Obesity, Gastroesophageal Reflux Disease (GERD), Shingles, Type 2 Diabetes, even Breast Cancer, and many more treatment programs coming soon. Track specific clinical signs with VELL Health: If you use a smart watch, smart ring, or other advanced wearable, you can automatically track clinical signs such as Heart Rate, Blood Pressure, Blood Glucose, A1C percentage, Blood Oxygen Saturation (sp02), Body Temperature, etc. but also physical activity (number of steps) and sleep (sleep time). These important measurements help you gauge your progress in managing your ailment. You may also enter clinical signs information manually if your medical devices are not connected. Work with your Care Provider: You can securely connect with your Care Provider(s) through VELL by simply exchanging a unique QR or code. Your care provider(s) will be able to track your progress and even warn you (or commend you) when or if specific situations arise. Your care provider(s) can also set up custom steps for you to follow.
