What kind of doctor treats Alcoholic Ketoacidosis?
An internist, an internal medicine doctor, usually treats alcoholic ketoacidosis in a hospital. Emergency doctors often start care. The condition is serious and needs quick treatment. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is alcoholic ketoacidosis?
Alcoholic ketoacidosis is the buildup of ketones in the blood due to alcohol use. Ketones are a type of acid. They form when the body breaks down fat for energy.
This problem is one form of metabolic acidosis. Metabolic acidosis means there is too much acid in body fluids. It usually starts after a person with heavy alcohol use suddenly stops drinking. It can also start after one bout of heavy drinking. By the time of testing, the blood alcohol level may be low or normal.
Symptoms
Symptoms of alcoholic ketoacidosis include:
- Nausea and vomiting.
- Pain in the belly.
- Agitation and confusion.
- Changed level of alertness, which may lead to coma.
- Tiredness and slow movements.
- Deep, labored, rapid breathing.
- Loss of appetite.
- Signs of dehydration, such as dizziness and thirst.
Doctors call the deep, rapid breathing Kussmaul breathing. The breath may smell fruity. These signs often start after a person suddenly stops drinking.
Causes and who gets it
Alcoholic ketoacidosis is caused by very heavy alcohol use. It most often occurs in a malnourished person who drinks large amounts of alcohol every day.
After heavy drinking, blood sugar and insulin levels fall. The body then breaks down fat for energy. Ketones then build up in the blood. The problem is mainly seen in people who drink heavily for a long time. It is rarely seen in binge drinkers. It can occur at any age.
How doctors diagnose it
Doctors check for signs that appear after drinking stops. Tests may include arterial blood gases. This test checks acid and oxygen levels in the blood. Other tests are a blood alcohol level, blood chemistries, liver tests, and a complete blood count (CBC). A CBC counts the cells in the blood.
Urine ketones may be checked. A blood test for beta-hydroxybutyrate, the main ketone, works better than urine tests. Blood potassium is often low. A blood value called the anion gap is often high.
Treatment
Treatment starts with fluids. A salt and sugar solution goes into a vein. This usually clears the ketones fast. Thiamine (vitamin B1) is important for people with alcohol problems, including ketoacidosis.
Replacing electrolytes is critical. Electrolytes are minerals like potassium, magnesium, and phosphate. Doctors check these levels and replace what is low. You may need frequent blood tests. Vitamin supplements can treat poor nutrition caused by heavy alcohol use.
People with this problem are usually admitted to the hospital. They often go to the intensive care unit (ICU). Stopping alcohol helps recovery. Medicines may be given to prevent alcohol withdrawal symptoms. Follow your doctor's instructions.
When to see a doctor
If you or someone else has signs of alcoholic ketoacidosis, such as deep, rapid breathing, confusion, or a change in alertness, call 911 or go to the emergency room. This can be a life-threatening condition. Problems may include coma and seizures, bleeding in the gut, an inflamed pancreas (pancreatitis), and pneumonia.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. After a hospital stay, your doctor can follow up on your recovery. Your doctor can also check for problems from heavy alcohol use, such as liver disease, and coordinate your care with specialists.
