AstraZeneca and ExaWizards develop an app for visualization of dietary and nutritional management for those concerned about their potassium levels including hyperkalemia
Recording the contents of 5 nutrients including potassium only by taking photos of everyday meals Jointly developing business that contributes to people’s health

 ExaWizards (Head Office: Minato-ku, Tokyo; President and Representative Director: Ko Ishiyama; hereinafter “ExaWizards”) developed AI food scanner “Hakarium” with AstraZeneca K.K. (Head Office: Kita-ku, Osaka; President and Representative Director: Takafumi Horii; hereinafter “AstraZeneca”) that develops services leveraging AI. “Hakarium” is an app with which potassium can be easily measured only by taking photos of meals.

  Hyperkalemia is a condition in which the serum potassium level is abnormally elevated. In Japan, more than 300,000 patients *1 have developed hyperkalemia mainly due to the progression of chronic kidney disease or other effects of meals, etc. Abnormally high serum potassium levels can cause fatal arrhythmias or cardiac arrest*2. Also, dietary and nutritional management of patients with hyperkalemia who have underlying diseases such as chronic kidney disease, dialysis, and heart failure are strictly restricted based on various guidelines.

 Hakarium was developed to enable people who are concerned about potassium levels, including patients with hyperkalemia, and their families to visualize and control the intake of diet and nutrition and thus enjoy their daily meals more. We aim to support appropriate communication between patients and healthcare professionals regarding dietary and nutritional management and to help patients independently manage their nutrition.
 ExaWizards is working with companies deploying the business in the healthcare area to develop the business that contributes to people’s health through taking advantage of AI. With this service release, we aim to provide more value to users.

 AstraZeneca will contribute to the support of dietary and nutritional management of patients with hyperkalemia who have underlying diseases such as chronic kidney disease, dialysis, and heart failure and be engaged in activities for as many people as possible to enjoy healthy and long life.
