What Organ Is on the Right Side Under the Breast?

Understanding the location of internal organs is important for recognizing potential health concerns. This region, known as the upper right quadrant of the abdomen, contains several organs that perform essential bodily functions.

The Liver: Location and Function

The largest organ in the upper right quadrant of the abdomen is the liver, tucked beneath the rib cage and partially under the right breast. It is a reddish-brown organ and is positioned above the stomach, right kidney, and intestines. The liver holds approximately one pint of the body’s blood supply at any given moment.

The liver performs many life-sustaining functions. One primary role involves detoxification, where it filters blood and removes harmful substances like alcohol and drugs, converting them into forms the body can excrete. Additionally, the liver is central to metabolism, processing nutrients from food, regulating blood sugar levels by storing and releasing glucose as needed, and producing proteins and cholesterol. It also produces bile, a fluid that aids in the digestion of fats and helps carry away waste products from the liver.

Additional Organs in the Vicinity

Other organs are also located within the upper right quadrant. Directly beneath the liver lies the gallbladder, a small, pear-shaped organ responsible for storing and concentrating bile produced by the liver. When food, particularly fats, enters the small intestine, the gallbladder releases bile to assist in digestion.

Parts of the large intestine are also found in this region. These sections play a role in absorbing water and electrolytes from digested food material, forming waste for excretion. Furthermore, the upper portion of the right kidney is situated in the posterior abdomen, just behind the liver. The kidneys are responsible for filtering blood to remove waste products and maintain the body’s fluid and electrolyte balance.

Recognizing Symptoms and Seeking Care

Discomfort or pain in the upper right abdominal area can stem from various sources. Mild, temporary symptoms like bloating or general discomfort might occur due to common issues such as indigestion or gas. However, persistent or severe pain can indicate a more serious underlying condition affecting the liver, gallbladder, or other organs in the vicinity.

Symptoms that warrant medical attention include sharp or severe pain that does not subside, persistent dull aches, or pain accompanied by fever, nausea, or vomiting. Other concerning signs are jaundice (yellowing of the skin or eyes), dark urine, pale stools, unexplained weight loss, or blood in the stool. Seeking professional medical evaluation is important for an accurate diagnosis and appropriate treatment of any persistent or worrying symptoms.
