- How do I get in touch with the dietitians? Send an email or call the number listed on the business cards.
- After the first week of full product, I want to change my food order, how do I do that? Email or fax your product order to one of the dietitians by Friday of the week before your next product pick up time.
- I am not able to make my usual product pick up time, what should I do? Call or email the dietitian to arrange an alternate product pick up time.
- I am experiencing some diarrhea what should I do? This could be due to intolerance to lactose. First try using the ready-to-drink (RTD) protein shake instead of the protein powder. If this does not solve the problem then use an OTC product like Lactaid taking one to two tablets with each product. If this is not effective, then add fiber to your program which helps by giving the stool more bulk. One can use OTC Imodium AD one to three capsules per day which will slow intestinal movements. You should let us know if the diarrhea is severe or lasts more than a couple of days. Watch for hidden sorbitol (in sugar-free gums) that can cause diarrhea as well.
- I am experiencing some constipation what should I do? Drink plenty of water and be physically active. Add fiber as the products do not contain much. Consider OTC products, which include both soluble and insoluble fiber, and take as directed (typically one tablet twice a day or one heaping teaspoon three times a day). For stubborn constipation, you can use a dose of a laxative such as OTC Miralax for relief (usually not necessary).
- I am feeling a little light headed what should I do? Increase your fluid intake. If it persists, contact us to discuss this further and we may consider using a soup for additional salt or medication adjustment if applicable.
