Sessions 2: Mid GI Symptoms
Early Satiation
Early satiation is the symptom of stomach fullness that occurs after a smaller amount of a meal, stopping one from finishing the full meal. It is a common symptom in many gastrointestinal diseases and therefore does not predict the underlying diagnosis. In this video, we will review potential causes, what key points to discuss with a medical provider, and what testing and treatments one may receive depending on the clinical situation and the ultimate diagnosis outcome.

Belching
Belching, commonly known as burping, is a normal way our body releases air. But when it occurs too often or interferes with daily life, it could signal a digestive problem. This presentation explains the two main types of belching: gastric belching, which happens when swallowed air exits the stomach, and supragastric belching, where air never actually reaches the stomach. Some causes include diet, acid reflux, anxiety, or simply swallowing too much air. Treatments range from avoiding carbonated drinks to breathing exercises and therapy. If belching is frequent or bothersome, it is important to talk openly with your doctor.

What Can I Eat? Dietary Options (FODMAP)
Wondering what you might be able to eat without triggering symptoms? Tune into this short video where we will explore how to follow the low FODMAP diet in a healthful and balanced manner!

Women’s Health in GI
Women are disproportionately affected by disorders of brain-gut interaction such as irritable bowel syndrome, but little is known why. In this discussion, I discuss the unique hormonal fluctuations and its influence on your gastrointestinal tract including the cycles of your period, perimenopause as well as menopause. Also, I discuss important diagnoses women know about, including endometriosis and pelvic floor dysfunction that can influence chronic symptoms of abdominal pain, diarrhea, constipation and more.

Bowel Urgency-Gastro Colic Reflux
Fecal urgency affects a large number of people. But did you know that there are certain instances where this actually makes sense. In this presentation, we will discuss how the body moves food and stool forward via a process called the gastro-colic reflex. We will also discuss what makes fecal urgency normal or abnormal, as well as how to approach a visit to the doctor to discuss this problem (don’t worry, we aren’t embarrassed by it). Finally, we will explain to you what can cause abnormal fecal urgency and how it might be treated. Tune in, your colon may just thank you for it later.

Incontinence
Fecal incontinence is the accidental loss of stool, which can be embarrassing and difficult to talk about—but you’re not alone, and help is available. It can be caused by problems with the muscles or nerves around the anus, diarrhea, constipation, or other medical conditions. Treatment depends on the cause and may include dietary changes, medications, pelvic floor exercises, or procedures to strengthen control. The most important first step is to speak with your doctor. Together, you can find a plan that works for you and helps you regain confidence and quality of life.

Low Blood Counts (Anemia)
This session will help you understand what it means to have a low red blood cell count, also known as anemia, and why it’s important not to ignore this “alarm sign.” We’ll explain what red blood cells do, the different reasons you might become anemic, and how anemia can sometimes point to hidden problems in the digestive system, like slow bleeding or even colon cancer. You’ll learn about common symptoms of anemia, when you should talk to your provider, and what questions to ask to make sure you get the care you need. By understanding these signs and being prepared to track your symptoms, you can play an active role in protecting your health.
