Myth 2 – Try taking guava juice, papaya leaves, 100 plus, crab soup etc. to increase your platelet count
...I do not advise them to take soft drinks (isotonic or not) as most of these drinks are very sweet. Taking them in large amount might cause diuretic effect, which makes you to urinate more frequently, and subsequently causing you to be dehydrated and feeling weaker instead....

3. Drink water, not 100 Plus

I’m not sure who started the whole “Drink 100 Plus” routine but you’re much better off drinking lots of water. Just water. Most carbonated drinks, including isotonic drinks, have high sugar content. Curing myself of dengue by giving myself diabetes doesn’t sound fun now, does it?

Frankly, I don't really agree with what the doctor said. Yes, drinking lots of 100 plus is not beneficial, but an adequate amount of it helps. When people fall sick, they have no appetite to eat, so the minerals in their bodies are not gonna get fully replenished if they only drink water and water will dilute the mineral level in their bodies as it will 'flush' them out of their bodies through urination. Isotonic drinks, in this case, will help the patients replenish the minerals and at the same time maintain the water concentration. Besides, directly linking diabetes to sugar intake is strictly not professional IMO when the truth is: High sugar intake ---> Increase body fats ---> Causes obesity ---> Affects endocrine system ---> Causes diabetes. From this flow, you can clearly tell obesity is the factor affecting it, not sugar intake alone.

Adequate fluid intake (more than 8 glasses or 2 litres for an average person).
- Milk, fruit juice (caution with diabetes patient) and isotonic electrolyte solution (ORS)
and barley water.
- Plain water alone is not sufficient and may cause electrolyte imbalance.
