Glucose is present in greyhound electrolyte supplements to provide energy, and assist with the uptake of potassium. A very complex system involving insulin acts to keep the greyhound’s blood glucose at a constant level. Giving any supplement which is high in glucose may stimulate the release of excessive Insulin. This is a natural hormone which stimulates cells to store glucose, thus decreasing blood glucose levels. This causes a reflex hypoglycemia where the blood glucose levels can become too low for a period of time.
Signs of low blood glucose (hypoglycemia) include:
• Lethargy
• Weakness
• Behavioral changes
To maintain a constant blood glucose level in greyhounds:
• Avoid giving supplements with high glucose content prior to racing
• If possible, avoid giving supplements with high glucose content on a regular basis
