Just a spoonfull of sugar is unlikely to take her sugars this high. But if she have had the hypoglycemia
since more than a few minutes, then the anti-insulin hormones get into action and raise the sugars beyond 12. This might be the case had she had a low which you people tried treating. Do check her sugars next time if you see her in similar weakness episode before you treat her with carbohydrates. If the sugar is not below 4.4 or 5, then she's not having low sugar and doesn't need to take sugar.
In this case, you make her undergo a certain tests which people with diabetes
need to undergo to understand deviations in their health perceptions like feeling unusually tired etc. Those tests are serum creatinine
, sodium, potassium, lipid profile
, HbA1c, urine microalbumin
and liver function tests. As of immediate action, you should have enlisted her medications here to let me reply most appropriately.
