Hi @leong. Certain classes of Antibiotics can cause low or widely fluctuating blood glucose levels. This is particularly prevalent with Ciprofloxacin, Moxifloxacin, Levofloxacin, Clarithromycin & Azithromycin. However, these classes of Antibiotics tends not to be prescribed for Gastroenteritis. Actually, Antibiotics are not usually recommended for treating gastroenteritis because many cases are caused by viruses rather than bacteria. Even when bacteria is responsible, antibiotics have often been found to be no more effective than simply waiting for the symptoms to pass. However, antibiotics may be recommended if you have particularly severe gastroenteritis and a specific bacterium has been identified in a stool sample.
In an effort to fight off illness or an infection, the body releases extra glucose into the blood stream. This can elevate your BG initially, but as your condition/illness improves, there can be a rebound effect upon the body, which may then plunge your BG into near hypo range. Which is what may be happening to you.
This must be very distressing & worrying for you. If you are still feeling unwell, Perhaps it would be wise to be medically reviewed. At least consider giving NHS Direct a call on 111. You will initially speak with a triage nurse, who will assess your need to be seen by a doctor. At the least, you'll be given some helpful advice.
I hope you are back on the road to recovery very soon. Best wishes.
