Dema Health

The DEMA is a wellness brand focused on at-home lymphatic care, particularly for people managing secondary lymphedema. Its central product, also called The DEMA, is a portable device designed to support manual lymphatic drainage by combining vibration therapy with strategic resistance. Made from flexible, medical-grade silicone, it fits in the palm and is intended to feel like an extension of the user’s hand, allowing people to adjust pressure and vibration to their comfort and apply drainage techniques across the body.

The device was developed by founder and CEO JeanAne Hecht, drawing on her experience as a breast cancer survivor living with secondary lymphedema. The brand presents The DEMA as an at-home tool to use between physical therapy or lymphatic massage appointments, with the aim of helping users manage fluid buildup, swelling, tightness, and discomfort. It also promotes the device for broader lymphatic wellness and relaxation. The company cites an at-home perception study involving patients with secondary lymphedema, in which visible results were reported in 88% of recorded treatment sessions.
