Addison’s disease can cause constant and persistent abdominal pain. Abdominal pain is any discomfort in any part of the belly, from the ribs to the pelvis. This pain is often referred to as ‘stomach ache’ or ‘stomach pain’. However, the pain can be coming from any of the internal organs besides the stomach. Abdominal pain occurs in several forms and may range from mild cramps to stabbing, sudden pains to a dull, constant aching.
Another symptom is depression. Addison disease can tamper with a person’s mood due to the effect of the inability to produce steroid hormones by the adrenal glands. This means that the stress levels in the body can no longer be maintained or managed, this can in turn result in depression.
Depression  is a medical condition that tampers with a person’s mood, which in turn affects their ability to function properly. Some symptoms of depression include feeling hopeless, sad or anxious. The condition can also cause difficulty with reasoning and thinking, eating, sleeping and memory. Without treatment, depression can go on for as long as possible, worsen and in extreme cases may result in self-harm or suicide.
