Organs on the Left Side of the Body

The main organs located on the left side of the human body are:

Heart: The heart is the central organ of the cardiovascular system and is located in the middle of the chest, slightly to the left of the sternum.

Stomach: The stomach is a J-shaped organ that lies in the upper left part of the abdomen, just behind the lower ribs.

Spleen: The spleen is an organ that filters blood and plays a role in the immune system. It is located in the upper left part of the abdomen, behind the stomach.

Pancreas (partially): The pancreas is an organ that produces hormones and digestive enzymes. The body of the pancreas extends across the upper abdomen, with the head on the right side and the tail on the left side.

Descending colon: The descending colon is the section of the large intestine that runs down the left side of the abdomen, connecting the transverse colon to the sigmoid colon.

Left kidney: The left kidney is one of the two kidneys, located in the left upper quadrant of the abdomen, just behind the stomach.

Left ovary (in females): The left ovary is one of the two female reproductive organs located in the lower left part of the abdomen.

These are the main organs located on the left side of the human body. The positioning and arrangement of these organs can vary slightly from individual to individual.

Common Causes of Pain in the Left Side Causes

1. Excess Gas

Gas pain can cause sharp, jabbing sensations or a general feeling of fullness and pressure in the abdomen, including the left side. This discomfort occurs when gas accumulates in your digestive tract, either from swallowed air or as a byproduct of food digestion by bacteria in your large intestine.

Common causes of excess gas include:

• Eating gas-producing foods (beans, lentils, broccoli, cabbage)
• Carbonated beverages
• Artificial sweeteners
• Eating too quickly or talking while eating
• Lactose intolerance
• Irritable bowel syndrome (IBS)

There are various ways to relieve pain caused by excess gas in the stomach. Some of the common home remedies include:

Home remedies for gas pain:

• Ginger tea: Ginger has anti-inflammatory properties that can help reduce gas and bloating
• Chamomile tea: Known for its anti-spasmodic effects that can relax your digestive tract
• Consuming light meals: Smaller, more frequent meals are easier to digest
• Peppermint oil or tea: Can help relax the muscles of your digestive tract
• Activated charcoal: May help absorb excess gas
• Gentle exercise: Walking can help stimulate the passage of gas
• Yoga poses: Certain positions, like Child’s Pose or Wind-Relieving Pose, can help release trapped gas

Additionally, over-the-counter medications like Pepto Bismol, simethicone products, or ibuprofen can be effective in relieving the pain. Drinking lots of water and avoiding acidic foods can also help reduce discomfort.

If you experience chronic gas pain that significantly impacts your quality of life, it’s worth consulting with a healthcare provider to rule out underlying conditions.

2. Indigestion

Indigestion, also known as dyspepsia, is a general term for discomfort in the upper abdomen. While it most commonly causes pain in the center or right side of the abdomen, it can also manifest as left-sided discomfort, especially when it’s related to stomach issues.

Common causes of indigestion include:

• Overeating or eating too quickly
• Fatty, greasy, or spicy foods
• Excessive caffeine, alcohol, or carbonated beverages
• Stress and anxiety
• Acid reflux or GERD (gastroesophageal reflux disease)
• Stomach ulcers
• Some medications, including aspirin and other pain relievers

Home remedies for indigestion:

• Drink plenty of fluids to aid digestion
• Chew gum after meals to increase saliva production, which can neutralize acid
• Avoid lying down for at least 2 hours after eating
• Eat smaller, more frequent meals
• Eliminate trigger foods from your diet
• Try herbal teas like ginger, peppermint, or chamomile
• Practice stress reduction techniques like deep breathing or meditation
• Use over-the-counter antacids for temporary relief

If you’re experiencing severe pain or discomfort in the abdomen, it is always best to consult a doctor. Chronic indigestion could be a sign of more serious conditions like GERD, ulcers, or even gallbladder issues.

3. Diverticulitis

Diverticulitis is a common condition that causes inflammation of the diverticula – small sacs or pouches that can form in the lining of your digestive system, most commonly in the large intestine or colon. When these pouches become inflamed or infected, they can cause significant pain, particularly on the left side of your abdomen.

Symptoms of diverticulitis include:

• Persistent pain in the lower left side of your abdomen
• Fever and chills
• Nausea and vomiting
• Constipation or diarrhea
• Bloating and gas

In most cases, treatment involves antibiotics to kill any infection present. For mild cases, your doctor might recommend a liquid or low-fiber diet until your symptoms improve. More severe cases may require hospitalization, intravenous antibiotics, or even surgery.

Home remedies for diverticulitis:

• Drink plenty of water to prevent constipation
• Follow a liquid diet during flare-ups to rest your digestive system
• Gradually introduce high-fiber foods when symptoms improve
• Use a heating pad on your abdomen to relieve pain
• Rest until your symptoms subside

Remember that while home remedies may provide temporary relief, diverticulitis requires proper medical treatment to prevent complications such as abscesses, perforation, or bowel obstruction.

4. Abdominal Hernia

An abdominal hernia occurs when an internal organ or tissue pushes through a weak spot in your abdominal muscles. While many hernias occur in the center or right side of the abdomen, certain types can cause pain on the left side.

Types of hernias that may cause left-sided pain:

• Hiatal hernia: The stomach pushes up through the diaphragm
• Incisional hernia: Occurs at the site of a previous surgery, potentially on the left side
• Spigelian hernia: Occurs along the edge of the rectus abdominis muscle, can be on either side
• Femoral or inguinal hernia: Can occur on the left side in the groin area

Symptoms of an abdominal hernia include:

• A visible bulge or lump in the affected area
• Pain or discomfort, especially when bending, coughing, or lifting
• A heavy or dragging sensation
• In some cases, nausea, vomiting, or fever (if the hernia becomes strangulated)

If you suspect you have a hernia, it’s important to see a doctor for a proper diagnosis. Hernias generally don’t improve without treatment and can lead to serious complications if left untreated.

5. Kidney Stones

Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. When these stones move through your urinary tract, they can cause excruciating pain. Since your left kidney is located on the left side of your abdomen, kidney stones in this kidney can cause severe left-sided pain.

Symptoms of kidney stones include:

• Severe pain in your side and back, below your ribs
• Pain that radiates to your lower abdomen and groin
• Pain that comes in waves and fluctuates in intensity
• Pink, red, or brown urine
• Cloudy or foul-smelling urine
• Nausea and vomiting
• Frequent urination
• Urinating in small amounts
• Fever and chills (if an infection is present)

Kidney stones can be quite painful and debilitating, especially if they are left untreated. Treatment depends on the size and cause of the stones, but many smaller stones will pass on their own with proper hydration.

Home remedies for kidney stones:

• Drink plenty of water (2-3 liters per day) to help pass the stone
• Try drinking mineral water, which may help with certain types of stones
• Limit sodium intake to reduce calcium in the urine
• Limit animal protein consumption
• Avoid foods high in oxalate if you have calcium oxalate stones
• Consider lemon juice or apple cider vinegar (diluted) to help dissolve certain stones
• Take over-the-counter pain relievers as needed

If you experience severe pain, blood in your urine, or signs of infection like fever and chills, seek medical attention immediately. Larger stones may require medical procedures for removal.

6. Lung

Your lungs occupy a significant portion of your chest cavity, with the left lung located on the left side of your chest. Various lung conditions can cause pain on the left side of your chest.

Lung conditions that may cause left-sided pain:

• Pneumonia: An Infection that inflames the air sacs in one or both lungs
• Pleurisy: Inflammation of the tissues that line the lungs and chest cavity

Remember that IBD is a chronic condition requiring ongoing medical care. These remedies should complement, not replace, treatments prescribed by your healthcare provider.

Pain in the Left Side Causes (Women Only)

The causes of left-sided pain are specific to women.

1. Pelvic Inflammatory Disease (PID)

Pelvic inflammatory disease (PID) is an infection of the female reproductive organs, typically occurring when bacteria from the vagina spread to the uterus, fallopian tubes, or ovaries. PID can cause pain on either side of the lower abdomen, including the left side.

Symptoms of PID include:

• Pain in the lower abdomen and pelvis
• Abnormal vaginal discharge with an unpleasant odor
• Painful or difficult urination
• Pain during intercourse
• Irregular menstrual bleeding
• Fever and chills

PID is a serious condition that requires prompt medical treatment with antibiotics. If left untreated, it can lead to complications such as infertility, ectopic pregnancy, or chronic pelvic pain.

Home measures to support medical treatment:

• Take all prescribed antibiotics exactly as directed
• Rest as much as possible during treatment
• Apply a heating pad to your lower abdomen to relieve pain
• Take over-the-counter pain relievers like ibuprofen
• Avoid sexual intercourse until treatment is complete
• Make sure your partner gets tested and treated if necessary

Always consult with your healthcare provider if you suspect PID, as early diagnosis and treatment are essential to prevent complications.

2. Ovarian Cysts

Ovarian cysts are fluid-filled sacs that form on the ovaries. Most ovarian cysts are harmless and resolve on their own, but some can grow large and cause pain or other symptoms. If a cyst develops on your left ovary, you may experience pain on the left side of your lower abdomen.

Symptoms of ovarian cysts include:

• Dull or sharp pain in the lower abdomen
• Bloating or swelling
• Painful bowel movements
• Painful intercourse
• Breast tenderness
• Nausea and vomiting

Most ovarian cysts don’t require treatment and will disappear on their own. However, large cysts or those causing significant symptoms may require medical intervention.

Home remedies for ovarian cyst discomfort:

• Take over-the-counter pain relievers like ibuprofen
• Apply a heating pad to your lower abdomen
• Take warm baths
• Practice relaxation techniques to manage pain
• Avoid activities that might cause the cyst to rupture, such as strenuous exercise or sexual intercourse
• Consider dietary changes that may help balance hormones, such as reducing processed foods and increasing anti-inflammatory foods

If you experience sudden, severe abdominal pain, especially with fever or vomiting, seek immediate medical attention as this could indicate a ruptured cyst or ovarian torsion.

3. Menstrual Cramps (Dysmenorrhea)

Menstrual cramps are painful sensations that affect many women before and during their menstrual period. These cramps often cause pain in the lower abdomen, which can radiate to the lower back and thighs. The pain may be more noticeable on one side, including the left side.

Causes of menstrual cramps:

• Contractions of the uterus to shed its lining
• Hormonal imbalances
• Conditions such as endometriosis or uterine fibroids
• Stress and poor diet
• Inflammatory chemicals called prostaglandins

Menstrual cramps can range from mild to severe, with some women experiencing debilitating pain that interferes with daily activities.

Home remedies for menstrual cramps:

• Apply heat to your abdomen with a heating pad or hot water bottle
• Take a warm bath with Epsom salts
• Try gentle exercise like walking or yoga

• Stay hydrated and avoid caffeine, alcohol, and salty foods

If your menstrual cramps are severe or getting worse over time, consult with a healthcare provider to rule out underlying conditions like endometriosis or fibroids.

4. Endometriosis

Endometriosis is a condition where tissue similar to the lining of the uterus grows outside the uterus. This tissue can be found on the ovaries, fallopian tubes, and the tissue lining the pelvis. When endometriosis affects structures on the left side of the pelvis, it can cause left-sided pain.

Symptoms of endometriosis include:

• Painful periods
• Pain during or after sexual intercourse
• Pain with bowel movements or urination
• Excessive bleeding during periods
• Infertility
• Fatigue, diarrhea, constipation, bloating, or nausea during menstrual periods

Endometriosis is a complex condition that requires medical management. Treatment options include hormonal therapies, pain medications, and in some cases, surgery.

Home remedies to complement medical treatment:

• Apply heat to your abdomen or lower back
• Take warm baths
• Practice yoga or gentle stretching
• Try acupuncture (with a qualified practitioner)
• Consider dietary changes such as reducing processed foods and increasing anti-inflammatory foods
• Try supplements like omega-3 fatty acids, turmeric, or N-acetylcysteine (after consulting with your doctor)
• Practice stress-reduction techniques
• Join a support group to connect with others who understand your experience

While these remedies may help manage symptoms, they should be used alongside medical treatment, not as a replacement.

5. Ovarian Torsion

Ovarian torsion occurs when an ovary twists on its supporting tissues, cutting off its blood supply. This is a medical emergency that requires immediate attention. If the left ovary twists, it can cause severe pain on the left side of the lower abdomen.

Symptoms of ovarian torsion include:

• Suddenly, severe pain in the lower abdomen
• Nausea and vomiting
• Fever
• Abnormal vaginal bleeding
• Dizziness or weakness

Ovarian torsion is most common in women of reproductive age and is often associated with ovarian cysts or previous pelvic surgery.

If you suspect ovarian torsion, seek emergency medical care immediately. Delayed treatment can result in loss of the ovary due to tissue death from lack of blood flow.

Pain in the Left Side Causes (Men Only)

These causes of left pain are specific to men.

1. Testicular Torsion

Testicular torsion occurs when a testicle rotates, twisting the spermatic cord that brings blood to the scrotum. This cuts off the blood supply to the testicle and surrounding tissues, causing sudden and severe pain and swelling. While the pain is primarily felt in the testicle itself, it can radiate to the lower abdomen, including the left side if the left testicle is affected.

Symptoms of testicular torsion include:

• Suddenly, severe pain in the testicle
• Swelling of the scrotum
• Abdominal pain that may radiate to the groin
• Nausea and vomiting
• A testicle that’s positioned higher than normal or at an unusual angle
• Fever
• Blood in semen

Testicular torsion is a medical emergency that requires immediate surgical intervention. Delayed treatment can result in the loss of the testicle due to tissue death from lack of blood flow.

If you suspect testicular torsion, seek emergency medical care immediately. Do not attempt to treat this condition at home or wait to see if symptoms improve.
