You might need to start insulin to get things under control if the level doesn't come back down soon. I would try DIA-IONX. DIA-IONX helps to control the symptoms of diabetes and it's therapeutic mineral base helps activate the enzyme systems in the body that help with healing. Some owners have told us it has helped stabilize the blood glucose levels. You can give DIA-IONX along with insulin. After giving DIA-IONX for a while some owners have reported that they have been able to reduce the insulin dosage and some have been able to stop giving it because it was no longer needed. However, each patient is unique and has its own set of circumstances. I prefer to add a half dose of DIA-IONX to the breakfast food and a half dose on the supper food. In addition I like to give probiotics, MSM, and Omega 3,6,9 daily. DIA-IONX will help the body better utilize the other supplements for a synergistic response. In addition make sure that you offer sufficient water free of chlorine and free of fluoride. A regular exercise schedule is also helpful in moving glucose from the blood and into the muscles which will reduce the blood glucose. It is important that you monitor the blood glucose levels so that you know how you are doing. Your veterinarian will probably recommend a low carbohydrate diet.
