Getting this right matters \u2014 arriving unprepared can mean rescheduling your appointment.<\/p>\n<h2>When Fasting Is Required<\/h2>\n<p><strong>Abdominal ultrasounds<\/strong> (liver, gallbladder, pancreas, spleen) usually require fasting for 6\u20138 hours. Food triggers your gallbladder to contract and fills your bowel with gas, both of which can hide the organs your sonographer needs to see. An empty stomach means a clear view.<\/p>\n<h2>When Fasting Is NOT Required<\/h2>\n<p>Most other scans need no fasting at all, including:<\/p>\n<ul>\n<li>Pelvic and pregnancy (obstetric) scans<\/li>\n<li>Thyroid and neck ultrasounds<\/li>\n<li>Musculoskeletal scans (shoulders, knees, tendons)<\/li>\n<li>Breast ultrasounds<\/li>\n<li>Vascular\/Doppler studies of the arms or legs<\/li>\n<\/ul>\n<h2>Practical Tips<\/h2>\n<p>Sips of plain water are usually fine even when fasting \u2014 and often encouraged. Avoid chewing gum and smoking before an abdominal scan, as both can introduce gas. If you&#8217;re diabetic or on essential medication, don&#8217;t skip your medicines; call the clinic ahead for guidance.<\/p>\n<p><strong>Key takeaway:<\/strong> Always follow the specific preparation instructions given when you book. If you&#8217;re unsure, ask before the day of your scan.<\/p>\n<hr \/>\n<p><em>This article is for general information only and is not a substitute for professional medical advice.<\/em><\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Ready to Book Your Ultrasound Scan?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Mascot Healthcare Clinic, Akoka (Yaba), Lagos offers ultrasound scans by appointment only, Monday\u2013Saturday, 9am\u20135pm.
