Constipation and nausea are most commonly caused by diet. A diet lacking in fiber and water is the most common cause of constipation, while overeating or eating ill-prepared foods can cause nausea. Various other circumstances, such as pregnancy or illness, can also cause nausea and constipation.
Many different physical ailments or conditions can cause constipation and nausea together. Specific conditions such as multiple sclerosis, lupus, spinal cord injuries, and diabetes can cause these symptoms to occur. The common flu or other temporary illnesses often cause constipation and nausea. Depression has also caused people to experience these unpleasant conditions.
Women who are pregnant often experience constipation and nausea. Diet modification and using gentle, physician approved aromatherapy, such as lemon slices, can often help provide nausea relief. People who rarely or never exercise may experience constipation and nausea. Regular physical activity, along with sufficient water and fiber intake, are required to keep bowel movements regular.
Certain trigger foods can cause constipation and nausea. A link between caffeine and nausea exists for many people. Foods that a person dislikes or associates with unpleasant memories may cause him or her to become nauseated upon smelling or eating them. People with an intolerance to specific foods such as gluten or dairy will usually experience nausea or constipation after eating them as well. Some foods, such as processed snacks and other low-fiber foods, can cause constipation in people who do not suffer from an intolerance as well.
A person's environment can lead to upset stomach and its symptoms. Many people experience nausea in extreme heat, or when frequently switching between a cool environment and a hot one. Nausea and stress can be related, too; some people experience nausea or vomiting when they are nervous, anxious, under excessive amounts of pressure, or in a new, unfamiliar environment. Traveling, especially by boat or airplane, can also cause the symptoms to occur.
General aging can cause irregularity in bowel movements. People who maintain a healthy lifestyle and still cannot relieve themselves of constipation should consult with a physician for a safe remedy. Many people experience nausea and constipation following a surgical procedure as well. If these symptoms persist, the patient should visit his or her doctor.
Some medications can cause constipation and other uncomfortable symptoms. Many prescription-strength pain medications, such as analgesics, can cause constipation. Doctors often prescribe stool softeners in conjunction with such medications in order to prevent discomfort. Certain anti-depressants, diuretics, antacids, and nutritional supplements can also cause bowel irregularity.
