Pre diabetes and lipid profile result.

Hi, my father is currently on Glycomet OD and Amaryl OD ( taking since March 2021). His latest blood sugar PP is 87.63, blood sugar fasting is 96.24 and HBA1c is 5.9. Does he still needs to take these medicines? Also, he has had angioplasty done in 2005 and currently taking Cresar H and Ecospirin AV apart from Parkinson medicines. In his latest lipid profile test, his total cholesterol is 121, HDL is 34, triglycerides is 208, LDL is 49, VLDL is 41.55, and LDL/ HDL is 1.4 are these concerning and we need to take any steps? He has also been taking syrup Lactihep and elixir neogadine since he had constipation issues. Now after taking green leafy veggie and fiber rich diet his constipation is gone. Does he still need to take these syrups?
