Lack of thirst

Hi my 16 year old daughter was diagnosed with high functioning autism in August 2017.  She has never drunk much and says she never experiences thirst.  This resulted in her being hospitalised this weekend for rehydration.  Even though my daughter is very intelligent I can't get her to believe that she needs to drink more.  Even though she ended up in hospital she had no physical shmptoms of dehydration, it was a blood test that highlighted it.  As far as my daughter is concerned no physical symptoms = not important.  Has anyone else any experience of no sensation of thirst with their ASC CHILD/adult?  Thank you.

  • I wonder if this could be something to do with us not always paying attention to what our bodies are telling us, especially when something else has our attention? I am notorious for getting so into something that I will forget to eat, or not realise that I need to go to the loo until the need is quite urgent. 

    When I was a kid I would not be aware of the need to eat until it got so urgent that I would feel ill, then it would often be too late as I would feel sick and unable to eat by that point. My perception was that the need to eat came on very suddenly, but I wonder if I was simply not aware of it until it became urgent? I had to start reminding myself to eat at regular intervals in order to avoid getting to this stage. I was even tested for diabetes several times as it is very similar to the kind of crash a diabetic person has if they don't add food for too long a period, but that was found to be not the problem.

    Perhaps establishing a routine of "at 10am you have your morning drink of squash and a biscuit" might help your daughter? If having a drink at certain points in the day becomes a habit rather than something she has to plan and think about (and be aware of the need for) it might work better for her. If you are with her, you could have a cup of tea at the same time and make it into a nice stop-and-relax moment for the two of you
