I am a Type 1 Diabetic myself and have been to Disneyland many, many times through the years, so I am very familiar with what your daughter's experience will be like. Thankfully, the tools that she has been given make managing a day at Disneyland very easy for someone with Type 1 Diabetes. Here are some things she should know.
First, the greatest challenge she will face is managing her blood sugar levels with all of the exercise she will be getting walking around the park. Her biggest danger will be from her blood sugar levels dropping too low because of all the exercise. Fortunately, she will be able to monitor her sugars very easily with the Dexcom G7. I just got the G7 myself and it is a game changer for diabetics in theme parks. I only wish I had had one for the past 40 years of park days.
The G7 will give her plenty of warning that her blood sugars are dropping and she can grab something sweet (soda, juice, candy or even delicious Disneyland treats if necessary
) to quickly raise them up a bit.
Because of the number of food outlets at Disneyland and their varied menus, your daughter will be able to find lots of food options in the park that will work with her diabetic diet. If she happens to consume a little too much carbohydrate/sugar, the G7 will show her sugar levels going too high and she can go to the restroom, or to first aid, and use her insulin pen (another thing I now use and wish I had had years ago) to give herself an injection and bring her blood sugar levels back down.
Speaking of insulin and first aid, your daughter will want to make sure that the pen needles don't get too warm on what can be a very hot day in the park. Thankfully, the first aid stations in the park are staffed by extremely helpful and compassionate cast members who are happy to take the pen needles and refrigerate them for you so that they don't overheat. She can come back to the first aid station and retrieve the pen needles to use whenever she needs to. For me, my first stop of the day in the park is at first aid to refrigerate my insulin and, like I say, the cast members there are wonderfully helpful.
I hope this information gives you and your daughter a better idea of what to expect during a day at Disneyland with Type 1 Diabetes. The good news is that the tools that are available nowadays make managing a day in the park with diabetes so much easier than it was for us diabetics back in the day. I know what you and your daughter are going through in learning about and adjusting to this newly diagnosed disease and I wish you all the best in successfully adapting to this medical condition and enjoying lots of fun and exciting days at Disneyland.
