Many sufferers are prescribed insulin to handle steroid-induced hyperglycemia and might want to measure their blood sugar extra often.[5]

Some chemotherapy medicines also can trigger hyperglycemia. Dr. Rariy says that this occurs when chemo medicine result in dehydration and electrolyte imbalances — too little or an excessive amount of sodium, potassium, chloride, or calcium within the blood and different bodily fluids.[6] Dehydration and electrolyte imbalances intrude with the physique’s means to manage glucose ranges, resulting in blood sugar spikes.[7]
Hyperglycemia generally is a results of widespread uncomfortable side effects of chemotherapy reminiscent of nausea, vomiting, or diarrhea. If sufferers can not eat or drink usually, it may well make blood sugar administration much more difficult, particularly for many who use insulin each time they eat.
Rariy identifies the next chemotherapy medicine as dangers for hyperglycemia:

- paclitaxel (Taxol)[10]
Focused Remedy and Immunotherapy

Whereas chemotherapy assaults all cells that divide quickly (together with wholesome ones), focused remedy assaults solely the most cancers cells, stopping them from multiplying and spreading.

Individuals with diabetes usually have sluggish wound therapeutic because of poor blood move or nerve harm, which makes the pores and skin much more prone to break down.[15]
Most cancers therapies also can worsen the long-term issues of diabetes in these methods:
- Each diabetes and sure most cancers therapies can result in nerve harm (neuropathy).[16] These two components, when mixed, may end up in elevated neuropathy signs like ache, numbness, tingling, and might make day by day actions difficult, Rariy says.
