24 Possible Causes for Fainting Spells, Nocturnal Leg Cramp

  • Hypoglycemia

    We present a case of an 85-year-old man who presented to the endocrinology clinic with symptoms of "fainting spells after large meals."[ncbi.nlm.nih.gov] Because of the history of Billroth II surgery and the description of his fainting spells, a 5-hour glucose tolerance test was performed in the clinic using the foods that[ncbi.nlm.nih.gov]

  • Chronic Alcoholism

    The concept of "structural plasticity" has emerged as a potential mechanism in neurodegenerative and psychiatric diseases such as drug abuse, depression, and dementia. Chronic alcoholism is a progressive neurodegenerative disease while the person continues to abuse alcohol, though clinical and imaging studies show[…][ncbi.nlm.nih.gov]

  • Peripheral Neuropathy

    Overview Peripheral neuropathy, a result of damage to the nerves outside of the brain and spinal cord (peripheral nerves), often causes weakness, numbness and pain, usually in your hands and feet. It can also affect other areas of your body. Your peripheral nervous system sends information from your brain and[…][mayoclinic.org]

  • Hyponatremia

    BACKGROUND: To investigate the prognostic value of hyponatremia, defined as serum sodium level METHODS: We performed a retrospective analysis of the RN patients (The patients included in our study had a history of primary cancers including nasopharyngeal carcinoma/glioma/oral cancer and received radiotherapy[…][ncbi.nlm.nih.gov]

  • Parkinson's Disease

    Oral surgery can be difficult in patients with chorea-like dyskinesia, which is common in those on long-term levodopa medication for Parkinson's disease, and we know of no conclusive evidence to indicate whether conscious sedation with midazolam is effective in such cases. We report a patient in whom levodopa-induced[…][ncbi.nlm.nih.gov]

  • Graves Disease

    Graves' disease is the most common cause of hyperthyroidism and is often managed with radioactive iodine (RAI) therapy. With current dosing schemes, the vast majority of patients develop permanent post-RAI hypothyroidism and are placed on life-long levothyroxine therapy. This hypothyroidism typically occurs within[…][ncbi.nlm.nih.gov]

  • Hypokalemia

    A 32-year-old woman with anorexia nervosa showing tall P waves on electrocardiogram (ECG) was reported. Her ECG showed tall P waves (5.5mm in voltage, lead II) at 2.2mEq/L of serum potassium. After the treatment, P waves decreased in voltage with the normalization of serum potassium. Tall P waves may be[…][ncbi.nlm.nih.gov]

  • Alcoholic Neuropathy

    Abstract Characteristics of alcoholic neuropathy have been obscured by difficulty in isolating them from features of thiamine-deficiency neuropathy. We assessed 64 patients with alcoholic neuropathy including subgroups without (ALN) and with (ALN-TD) coexisting thiamine deficiency. Thirty-two patients with[…][ncbi.nlm.nih.gov]

  • Insulinoma

    A 71-year-old woman previously diagnosed with reactive hypoglycemia was transferred to our emergency unit because of loss of consciousness. Her plasma glucose level was 27 mg/dL, and continuous glucose monitoring (CGM) revealed postprandial asymptomatic hypoglycemia. A hypervascular tumor was identified via[…][ncbi.nlm.nih.gov]
