(1) Lack of exercise. Weak and unused muscles in your back and abdomen might lead to back pain.
(2) Improper lifting. Using your back instead of your legs when lifting a heavy object can lead to back pain.
(3) Age. Back pain is more common as you get older.
(4) Excess weight. Excess body weight puts extra stress on your back and this might lead to back pain.
(5) Diseases. Some types of arthritis and cancer can contribute to back pain.
(6) Psychological conditions. People prone to depression and anxiety appear to have a greater risk of developing back pain.
(7) Smoking. This may occur because smoking prompts more coughing which can lead to a herniated disc. Smoking can also decrease blood flow to the spine and increase the risk of osteoporosis.
