Internal Medicine and Beyond: The Comprehensive Approach to Wellness


When you’re sick, it can be overwhelming to know where to start. With so many parts of the body and so many different illnesses, it’s difficult to know what information you need up front. In this manual, Dr. Manuel Abreu, cover all the basics: from understanding your blood sugar to controlling diabetes, this handbook will provide everything you need to know before heading into an appointment with your primary care provider or talking with a specialist.

Introduction to Internal Medicine

Internal medicine is a medical specialty that focuses on the diagnosis and treatment of adult diseases. Physicians who practice internal medicine are trained to provide comprehensive care for patients with complex medical problems, including those who are at risk for developing serious illnesses such as heart disease or diabetes.

Internal medicine physicians can be board-certified in one of two ways: by completing an undergraduate degree in pre-medicine followed by four years of medical school; or through an accelerated program that allows students to earn both degrees within seven years.

The internal medicine approach to wellness involves identifying and managing health risks such as high blood pressure or cholesterol levels before they become serious illnesses like heart attack or stroke.”

The Body

The human body is made up of tissues and organs. Tissues are collections of cells that perform specific functions. Organs are composed of tissues, and they perform vital bodily functions such as digestion or respiration. Each organ has its own structure and function, but they all work together to keep the body alive and healthy.

The cells that make up each tissue or organ have specific shapes, sizes, structures and functions that allow them to perform their jobs efficiently (for example: red blood cells carry oxygen throughout the body; muscle fibers contract when stimulated). Cells can be further divided into smaller units called organelles (for example: mitochondria produce energy by breaking down nutrients). Organelles themselves consist primarily of proteins surrounded by membranes made up mostly lipids (fats) with some carbohydrates attached too! And finally these molecules are made up even smaller particles called atoms which contain protons neutrons electrons neutrinos photons etc…

The Heart and Blood Vessels

As you know, the heart is a muscle. It’s also a pump and a valve, but what else does it do?

The heart is the reservoir for blood volume and regulates blood pressure by releasing hormones into the bloodstream that increase or decrease blood flow throughout the body. It also controls cardiac output (the amount of blood pumped out per minute), which determines how much oxygen gets delivered to muscles during exercise. This means that if you want to be able to run faster or lift heavier weights, then you’ll need to work on strengthening your cardiovascular system through exercise!

The Lungs and Airways

The lungs are a pair of organs that reside in the chest. They are responsible for taking oxygen from the air, transporting it to your blood and releasing carbon dioxide back into the atmosphere. The lungs have a large surface area, which allows them to absorb oxygen from the air at a high rate (about 20 times faster than other organs).

The respiratory system also includes your nose, throat and windpipe (trachea). This part of your body helps you breathe by providing an opening through which air can enter or leave your body as well as protecting sensitive tissues inside your nose and mouth from injury during breathing activities like coughing or sneezing.

The Gastrointestinal Tract

The gastrointestinal tract is the part of your body that processes food and beverages. It begins at the mouth of your throat, continues through your stomach and then into the small intestine (or small bowels) and large intestine (or colon).

The esophagus carries food from your mouth to your stomach. The stomach then breaks down food before passing it along to the small intestines, where nutrients are absorbed into blood vessels that carry them throughout your body. The remaining waste products continue on through another set of arteries which lead into a third organ called an appendix–if you have one! This tube attaches itself directly onto what’s called “the vermiform” or “wormlike” appendix that lies next door inside our bodies; this structure helps protect us from infection by trapping harmful bacteria before they get inside our bodies through wounds caused by accidents such as falling off bikes onto pavement surfaces like concrete sidewalks where there aren’t any plants growing nearby yet either so no one knows why some people still prefer riding bikes over walking since both forms of transportation require exercise anyway…

The Kidneys, Bladder and Urine

The kidneys are two bean-shaped organs that lie just below the rib cage on either side of your spine. The kidneys filter blood and remove waste from your body. They also help regulate blood pressure and maintain fluid balance in your body.

Kidneys can be damaged by disease, drug use or injury. When this happens, you may have pain in your side or lower back ( flank pain ), nausea and vomiting, unusual tiredness or weakness ( fatigue ), swelling around one ankle–especially when you stand up after lying down for a while ( edema ). If your kidneys fail completely:

  • You’ll have to change what goes into your mouth so that it’s gentler on them–no caffeine drinks like coffee or cola; no salt on food; no alcohol beverages; no foods high in potassium such as bananas; no chocolate desserts because they contain caffeine along with sugar which will increase fluid loss through urination thus requiring additional fluid intake beyond normal amounts required daily which could lead to dehydration if not careful about how much liquid consumed daily per person’s weight classifications based upon height/weight ratio calculations made during childhood development stages so keep track of these numbers throughout life so as not too overdo anything too much especially during stressful times where emotions run high due to excitement about upcoming events like vacations where stress levels tend rise drastically due

The Musculoskeletal System and Nervous System

The musculoskeletal system includes the bones, joints, muscles and tendons. It provides support for the body and allows us to move. The nervous system consists of two parts:

  • The brain controls body functions such as breathing or heartbeat.
  • Nerves send signals from your senses (like sight) or muscles (such as those in your arms) to other parts of your body so that you can move them properly.

Diabetes and Blood Sugar Control Methods

Diabetes is a disease of the pancreas that affects your body’s ability to make and use insulin. Insulin is a hormone that helps your cells absorb glucose (a type of sugar) for energy.

The treatment for diabetes depends on its type:

  • Type 1 diabetes–caused by an autoimmune reaction, this form usually occurs in children or young adults who may need daily injections of insulin as well as other medications to control blood sugar levels
  • Type 2 diabetes–most often caused by poor diet and lack of exercise; this form can be managed with medical treatment that includes oral medications and/or insulin injections

This manual can help you understand your own internal workings.

This manual can help you understand your own internal workings. It doesn’t offer medical advice, but it does provide basic information about the parts of your body and how they work together. The topics covered include:

  • Your heart and blood vessels (cardiovascular system)
  • Your lungs and airways (respiratory system)
  • Your gastrointestinal tract (digestive system)


We hope you have learned a lot about the internal workings of your body, and how to keep it healthy. If there are any questions about what we covered here today, please don’t hesitate to ask! We love helping people understand their bodies better, so please let us know if there’s anything else we can do for you.
