<s>[INST] does tums increase the glucose in blood..currently i am pregnant and i forgot to took glucose tasteafter 1 hour..i took it within 1 hour and reading came 122 and after 1 hour when i took taste i had tums and reading came 147..is it because of tums or 10 minute difference? [/INST] Tums for Tummy, is that the one you are referring! If so, TUMS is high in Calcium and little of Sugar, however, the marginal rise of sugar u observe could be due to Pregnancy itself. Pregnancy is a diabetogenic state, so these values suggest getting a Glucose Tolerance Test. TUMS is safe, in pregnancy. If the OUT is positive then u can get a sugar-free TUMS, but that contains Glutamate, only take it if u have no history of allergies. </s>
