2. Rheumatoid Arthritis
While weight gain isn’t exactly a symptom of RA, it’s common for persons with the ailment to slowly pack on pounds. This occurs when the steroids commonly used to reduce inflammation, cause weight gain and water retention instead; resulting in tender joints, stiffness, and fatigue—making it difficult to maintain normal activity.

- Pain or aching in more than one joint
- Stiffness in more than one joint
- Tenderness and swelling in more than one joint
- The same symptoms on both sides of the body (such as in both hands or both knees)
- Weight loss
- Fever
- Fatigue or tiredness

1. Crohn’s Disease and Ulcerative Colitis
Typically grouped together, these inflammatory bowel diseases are caused by an abnormal immune response. While ulcerative colitis only affects the colon, Crohn’s can wreak havoc on any part of the gastrointestinal tract. Both disorders may cause changes in the eyes, mouth, and skin, diarrhea, abdominal pain, and even weight loss, due to an inability (or lack of desire) to eat. According to a 2007 study, Crohn’s sufferers also experience a higher frequency of kidney stones, when compared to the rest of the population.
