Hello welcome to the health care magic Regularly take prescribed medication for hypertension and high cholesterol... And let me inform medicines which you are taking... Change in period is because you are near menopause... For bloating causes are... -lack of physical activity -too much fatty foods -stress -Smoking -eating too fast -Excess soft drink usage -irritable bowel syndrome -celiac disease etc... So above factor should be ruled out Take more fiber diet like wheat bran, whole grain, green leafy vegetables etc... Avoid excess spicy foods and fatty meals If constipation associated then ispghula husk with milk can be prescribed Drink more water If no improvement USG abdomen needs to be done Take care Hope your concern solved
