Choose the right tools. Stay informed. Your heart, kidneys, eyes\u2014and quality of life\u2014depend on it. FAQs: How often should I check my blood sugar? It depends on your type of diabetes and treatment. Type 1 diabetics may check multiple times daily; Type 2 diabetics may check less frequently, depending on medication and control. What\u2019s the normal blood sugar range? Before meals: 80\u2013130 mg\/dL.1\u20132 hours after eating: Less than 180 mg\/dL. What\u2019s the difference between a glucose meter and a CGM? A glucose meter gives single readings via fingerstick; a CGM provides real-time, continuous data and trends with fewer fingersticks. Can I use a CGM without a prescription? Most CGMs require a prescription in the U.S., though some over-the-counter options may become available soon. Do I still need fingersticks if I use a CGM? Some CGMs still require occasional calibration with fingersticks, but many newer models are factory-calibrated and do not.<\/p>\n","protected":false},"author":2,"featured_media":6426,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"footnotes":""},"categories":[2,6,9],"tags":[2375,176,2378,18,186,104,2379,21,12,33,2376,174,193],"class_list":["post-6425","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-articles","category-diseases-conditions","category-health-issues","tag-blood-sugar","tag-causes","tag-cgm","tag-disease","tag-happylife","tag-healthylife","tag-meter","tag-o-health","tag-ohealth","tag-ohealthtv","tag-sugar-monitoring","tag-treatment","tag-wellness"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts\/6425","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/comments?post=6425"}],"version-history":[{"count":1,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts\/6425\/revisions"}],"predecessor-version":[{"id":6427,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts\/6425\/revisions\/6427"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/media\/6426"}],"wp:attachment":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/media?parent=6425"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/categories?post=6425"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/tags?post=6425"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
