Keto Acidosis And Protein In Urine: What's The Link?

Diabetic ketoacidosis (DKA) is a serious complication of diabetes. It occurs when the body cannot produce enough insulin, which is a hormone that helps sugar enter cells in the body. Without enough insulin, the body starts breaking down fat as fuel, leading to a buildup of acids called ketones in the bloodstream and urine. This condition is called ketoacidosis and can be life-threatening. While small amounts of ketones in the urine are normal, high levels can indicate that the body is too acidic, which can be dangerous. In addition to diabetes, other factors that can increase the risk of ketoacidosis include vomiting, diarrhea, alcohol use disorder, eating disorders, starvation, certain digestive diseases, and intense exercise.

Proteinuria, on the other hand, refers to elevated protein levels in the urine, indicating that the kidneys are not filtering blood correctly. Dehydration, high blood pressure, diabetes, and chronic kidney disease are some of the common causes of proteinuria. While proteinuria itself is not a disease, it can be a sign of underlying kidney conditions or other health issues.

So, while ketoacidosis can cause an increase in ketones in the urine, it is less likely to directly cause proteinuria. However, the presence of both ketones and protein in the urine could indicate underlying health issues, such as diabetes or kidney dysfunction, that require medical attention.

Diabetic ketoacidosis (DKA)

DKA usually develops slowly, but symptoms can appear quickly and be life-threatening. Early symptoms include frequent urination, while more severe symptoms can include fast and deep breathing, fruity-scented breath, muscle stiffness or aches, nausea, and vomiting. DKA can sometimes be the first sign of diabetes in people who haven't yet been diagnosed.

The two most common causes of DKA are illness and problems with insulin therapy. Illnesses such as infections or injuries can cause the body to make higher levels of certain hormones that work against the effects of insulin. Problems with insulin therapy can include missed insulin doses, a clogged insulin pump, or an incorrect insulin dose. Other causes of DKA include heart attack, stroke, alcohol or drug misuse, and certain medications.

People with type 1 diabetes are at the highest risk of developing DKA, but it can also occur in people with type 2 diabetes, especially in situations of extreme stress or acute illness.

To prevent DKA, it is important to monitor blood sugar levels frequently, keep blood sugar levels within the target range, take medications as prescribed, and adjust insulin doses as needed in consultation with a healthcare provider. If you are experiencing symptoms of DKA, it is important to test for ketones in the urine or blood and seek medical attention as soon as possible, as untreated DKA can lead to severe illness or death.

The treatment for DKA aims to correct high blood sugar levels with insulin, replace lost fluids and electrolytes, and address any underlying causes such as infections. Most people respond to treatment within 24 hours, but it can sometimes take longer to recover.

Alcoholic ketoacidosis (AKA)

AKA is typically seen in patients with chronic alcohol use disorder and those who binge drink. Patients are usually chronic drinkers who are unable to tolerate oral nutrition for a period of 1 to 3 days. They often have a recent history of heavy drinking, persistent vomiting, and abdominal pain, which contribute to their inability to eat.

The diagnosis of AKA is made on a clinical basis. Patients typically present with tachycardia, dehydration, tachypnea, abdominal pain, and agitation. They may also have a ketone odour on their breath. Dehydration causes an elevated heart rate and dry mucous membranes, and alcohol withdrawal can lead to agitation. Abdominal pain may be secondary to alcoholic gastritis or pancreatitis.

The treatment of AKA involves fluid resuscitation, monitoring of electrolytes, and prevention of alcohol withdrawal. It is important to give isotonic fluid resuscitation, such as normal saline with dextrose, to break the cycle of ketogenesis and increase insulin secretion. Thiamine should be administered before glucose-containing solutions to prevent Wernicke's encephalopathy.

The prognosis for patients with AKA is generally good if the condition is identified and treated early. However, delayed diagnosis or under-resuscitation can lead to complications such as hypovolemic shock and cardiac arrest. The long-term prognosis is influenced more by recovery from alcoholism than AKA itself.

Starvation ketoacidosis

The transition from ketosis to ketoacidosis typically occurs after 2-3 days of fasting. If starvation continues beyond this point, the body will start to break down muscle tissue, releasing amino acids and lactate into the bloodstream. The liver then converts these substances into sugars to use as fuel. This process can lead to a range of symptoms, including weight loss, lower body temperature, sparse hair, and prominent bones. In severe cases, individuals may experience lethargy and a loss of strength as their bodies begin to break down muscle.

It is important to note that starvation ketoacidosis is different from diabetic ketoacidosis and alcoholic ketoacidosis, although these conditions may coexist. Diabetic ketoacidosis occurs when the body cannot produce enough insulin, leading to a buildup of ketones in the blood. Alcoholic ketoacidosis, on the other hand, is commonly seen in individuals who drink excessive amounts of alcohol and are unable to eat solid food due to symptoms such as vomiting and anxiety.

Ketone testing methods

There are three basic categories of ketone testing: blood, breath, and urine. Each method of testing measures something different: blood tests measure β-hydroxybutyrate levels, breath tests measure acetone levels, and urine tests measure acetoacetate levels. β-hydroxybutyrate, acetoacetate, and acetone are all ketones produced during fat metabolism.

Blood Testing

Blood ketone meters require a battery and a test strip for each test (about $1/strip) as well as disposable lancets. The process involves pricking your finger to produce a very small drop of blood for testing. Blood tests give accurate readings of your current ketone levels and are less messy to use. However, they are more expensive than urine tests and require a machine meter to operate.

Breath Testing

Breath tests measure the amount of the ketone acetone in your breath in parts per million (ppm). Breath tests are painless and do not require the purchase of extra supplies like lancets or strips. Reliable breath-testing devices are fairly expensive and slightly less accurate than blood testing. Breath tests are also affected by alcohol consumption, with one source recommending that you wait until alcohol is completely out of your system before testing.

Urine Testing

Urine tests are the least expensive way to test for ketones. They are also easy to use, as they are usually test strips that you dip into your urine. Urine tests are, however, the least accurate testing method and can be affected by dehydration.

Diabetic ketoacidosis symptoms

Diabetic ketoacidosis (DKA) is a serious and potentially life-threatening complication of diabetes. It occurs when the body does not produce enough insulin, which is necessary for sugar (glucose)—a major energy source for muscles and other tissues—to enter cells. Without enough insulin, the body starts breaking down fat for energy, leading to a buildup of acids called ketones in the bloodstream. If left untreated, this buildup can lead to DKA.

DKA symptoms often come on quickly, sometimes within 24 hours, and for some, these symptoms may be the first indication of diabetes. Early symptoms of DKA include:

• Urinating a lot more than usual
• Fast, deep breathing
• Fruity-smelling breath
• Muscle stiffness or aches
• Nausea and vomiting

If DKA is left untreated, more severe symptoms can develop, such as:

• Extreme thirst (polydipsia)
• Extreme hunger (polyphagia)
• Shortness of breath or Kussmaul breathing
• Feeling very tired or weak
• Feeling disoriented, agitated or confused (altered mental status)
• Decreased alertness
• Stomach pain

Untreated, DKA can lead to loss of consciousness and even death. Therefore, it is crucial to seek immediate medical attention if you are experiencing any of these symptoms.
