Beer And Kidney Disease: What You Need To Know

Alcohol is a diuretic, which means that it causes the body to remove fluid faster, leading to dehydration. This poses a challenge for people with kidney disease, who often need to restrict their fluid intake. Alcohol can also negatively impact kidney function and increase the risk of chronic health conditions like high blood pressure. However, according to some sources, consuming one standard drink per day (1.5-oz shot, 12-oz beer, or 5-oz wine) does not increase the risk of developing kidney disease. For those with kidney disease, it may be safe to continue consuming alcohol occasionally, but it is important to monitor blood pressure and heart rate, watch fluid intake, and be mindful of any medications that may interact with alcohol.

Alcohol's impact on kidney function

Healthy kidneys work to remove excess waste, toxins, and fluids from the blood. Alcohol is one of the toxins that the kidneys filter, and excessive alcohol consumption can weaken the kidneys, preventing them from filtering the blood properly. This can lead to a build-up of fluids in the body, causing swelling and difficulty breathing. Additionally, alcohol can cause dehydration, impairing the kidneys' ability to maintain the right balance of fluids in the blood. Dehydration can also affect the normal function of cells and organs, including the kidneys.

Drinking alcohol can also increase blood pressure, which is a common cause of kidney disease. High blood pressure can, over time, increase the risk of heart attack and stroke. Alcohol can also disrupt hormones that affect kidney function. For those with kidney disease, the impact of alcohol on blood pressure and kidney function can be particularly harmful.

The interaction of alcohol with medications is another important consideration. Alcohol can cause certain medications to have a stronger effect or render them less effective. This includes diabetes medication, heart medication, sleeping medication, and pain medication. For those with kidney disease, the impact of alcohol on medication effectiveness can be a serious concern.

While moderate alcohol consumption may be considered safe for those with chronic kidney disease who are not on dialysis, it is always advisable to consult with a doctor or dietitian. They can provide personalized guidance based on an individual's diet, health needs, and medication. For those with kidney disease, it is crucial to monitor alcohol consumption and be mindful of its potential impact on kidney function and overall health.

Alcohol's interaction with medication

Alcohol interacts with many medications, including diabetes medication, heart medication, sleeping medication, pain medication, and more. The interactions can cause a wide range of side effects, from nausea and vomiting to increased risk of internal bleeding, heart problems, and breathing difficulties. Alcohol can also make a medication less effective or even useless, or it may make the medication harmful or toxic to your body.

For example, the combination of opioid painkillers and alcohol should be avoided as it can slow or stop breathing and may even be deadly. Drinking while taking steroids or anti-inflammatory medications can lead to stomach bleeding and ulcers. Alcohol can also intensify medication side effects such as sleepiness, drowsiness, and light-headedness, which may interfere with your concentration and ability to operate machinery or drive a vehicle.

Older people are at a particularly high risk of harmful alcohol-medication interactions. Aging slows down the body's ability to break down alcohol, so it remains in the system longer. Older people are also more likely to take medications that interact with alcohol. Women are also more susceptible to alcohol-related organ damage, as alcohol reaches a higher level in their bloodstream compared to men due to having less body water.

It is important to observe warning labels and ask your doctor or pharmacist if it is safe to consume alcohol with any medications or herbal remedies you are taking.

Alcohol and blood pressure

Alcohol can have a significant impact on blood pressure, and this is an important consideration for individuals with kidney disease. Excessive alcohol consumption can lead to an increase in blood pressure, which can have adverse effects on overall health.

According to research, there is a clear association between the number of alcoholic beverages consumed and an increase in systolic blood pressure. This relationship was observed even in individuals without hypertension, indicating that alcohol can contribute to higher blood pressure levels over time, regardless of existing conditions. The analysis of seven international studies found that each additional alcoholic drink per day was linked to a rise in blood pressure.

For individuals with kidney disease, managing blood pressure is crucial. Alcohol can interact with medications commonly prescribed for kidney disease, such as diabetes medication, heart medication, and sleeping pills. These interactions can enhance or reduce the effectiveness of the medication, leading to potential complications. Therefore, it is essential to consult a pharmacist or physician before consuming alcohol while taking any medication.

The American Heart Association provides guidelines for alcohol consumption, recommending no more than two drinks per day for men and one drink per day for women. These guidelines are intended for individuals who choose to drink and aim to help manage blood pressure. It is important to note that alcohol consumption does not provide any additional health benefits, and limiting or avoiding alcohol is generally advised for maintaining optimal cardiovascular health.

While the impact of alcohol on blood pressure is a concern, it is not the sole contributor to increased blood pressure. Other factors, such as age, lifestyle, and overall health, also play a role. However, for individuals with kidney disease, it is crucial to monitor alcohol intake and be mindful of its potential effects on blood pressure and overall kidney function.

Alcohol's effect on blood sugar levels

Alcohol can have a significant impact on blood sugar levels, particularly for people with diabetes. When a person consumes alcohol, it is rapidly absorbed by the stomach and small intestine and enters the bloodstream. As a depressant, alcohol suppresses the central nervous system.

The liver, which normally breaks down and releases glucose (sugar) into the bloodstream, especially between meals and while sleeping, finds it challenging to perform this function when alcohol is present in the body. Instead, the liver focuses on breaking down alcohol. Consequently, blood sugar levels fluctuate and can drop too low, a condition known as hypoglycaemia. This risk is heightened when drinking on an empty stomach, and it increases with each additional drink.

Alcohol can also affect the body's ability to regulate blood sugar. It can cause blood sugar levels to drop, especially if food intake is insufficient. Conversely, consuming excessive amounts of alcohol and food can lead to elevated blood sugar levels.

For individuals with diabetes, alcohol can have additional implications. It can increase appetite, leading to overeating and further elevating blood sugar levels. Alcoholic drinks are often high in calories, making weight loss more difficult. Alcohol can also interfere with diabetes medications, reducing their effectiveness. Moreover, some symptoms of excessive alcohol consumption, such as flushing, nausea, increased heart rate, and slurred speech, can be mistaken for symptoms of low blood sugar. This overlap of symptoms can make it challenging to determine whether one has consumed too much alcohol or if their blood sugar is dangerously low.

It is recommended that people with diabetes drink in moderation and only when their blood sugar levels are well-controlled. Consulting a doctor is advisable to understand the risks and receive guidelines based on individual health concerns. Checking blood sugar levels before and after drinking, as well as up to 24 hours later, is crucial for people with diabetes.

Safe levels of drinking

If you have kidney disease, it is important to be mindful of how much you drink and the effects that alcohol can have on your body.

The federal government's Dietary Guidelines for Americans defines moderate drinking as: one drink per day for women and older people, and two drinks per day for men. These limits differ because men usually weigh more and alcohol is processed differently by the sexes. Women tend to have a stronger reaction to alcohol because they have less water in their bodies, so the alcohol becomes more concentrated. The risk for alcohol-related diseases is also higher in women than in men.

One drink is defined as 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of hard liquor. Consuming an occasional glass or two of an alcoholic beverage usually won't cause harmful effects for individuals with full kidney function. However, when drinking alcohol with chronic kidney disease, even a modest amount of alcohol could negatively impact your health.

For people with chronic kidney disease (CKD) who are on a low-potassium and/or low-phosphate diet, choosing suitable drinks can be challenging. Some wines and beers contain high levels of potassium and phosphate. For those who need to limit their fluid intake to less than 1 litre (2 pints) a day, including one of these drinks can significantly impact their total fluid consumption.

The recommendations for alcohol consumption for people with kidney disease are the same as for the general population: not to drink more than 14 units a week (for both men and women). It is important to note that alcoholic drinks come in different strengths and sizes, so it's not as simple as one drink, one unit. For example, one unit is equivalent to a single measure of spirits (ABV 37.5%), half a pint of average-strength (4%) lager, or two-thirds of a 125ml glass of average-strength (12%) wine.

If you are experiencing symptoms of kidney disease or are living with chronic kidney disease, limiting your alcohol consumption can help preserve your kidney function.
