Health disorders with dizziness as a symptom include angina, chronic fatigue syndrome, dehydration, diabetes and diverticulitis, states MedicineNet. Other possible causes include high blood pressure, hyperthyroidism, hypothyroidism, hypoglycemia and multiple sclerosis, as well as stroke and vertigo.
One of the basic causes of dizziness is vertigo, a condition caused by inner ear issues, explains Mayo Clinic. Either the inner ear structures are imbalanced for a short period of time or there is an issue with the way the structures connect to the brain. Depending on the reasons for this imbalance, the dizziness can occur in short or long episodes. Dizziness caused by benign paroxysmal positional vertigo is not serious and occurs with sudden changes of position of the head. Inflammation of the inner ear causes dizziness and imbalance but resolves itself eventually.
Sometimes dizziness can be a result of more serious problems such as Meniere's disease, a condition with inner ear fluid buildup, according to Mayo Clinic. This can cause periods of imbalance and dizziness, as well as hearing loss that can last for short or long periods of time. Noncancerous growths that grow in the inner ear can cause progressively worsening vertigo and hearing loss. Sometimes anxiety disorders and certain medications can cause dizziness and a feeling of floating.
