Low back pain can have many causes, including:● Pregnancy.● Obesity: Carrying extra weight, especially in the form of belly fat, puts strain on the lower back. This strain can lead to pain and inflammation.● Stress.● Poor physical activity.● Poor posture: Slouching or sitting in a hunched position can also cause lower back pain. This is because it puts unnecessary strain on the spine.● Improper lifting: Lifting heavy objects without proper form can cause the muscles and ligaments in the lower back to become strained and result in pain.● Age: As you age, the discs in your spine begin to degenerate. This can lead to pain and stiffness in the lower back.● Herniated discs: A herniated disc occurs when the inner material of spinal discs leaks out and puts pressure on the nerves surrounding it. When the nerves become compressed, it can cause pain.● Degenerative disc disease: This is a condition that occurs when the discs in the spine begin to break down. It can lead to pain, stiffness, and inflammation.● Poor sleep.● Ruptured or herniated discs.● Arthritis.● Scar tissue from a previous back injury.● Smoking.● Dietary deficiencies.● Nonspecific low back pain.
