Why does apple juice make me constipated?

Constipation is a common condition affecting people of all ages. While apple juice is often thought of as a healthy drink, some people find that drinking too much apple juice has the unpleasant side effect of causing or worsening constipation. This article explores why apple juice can lead to constipation, who is most at risk, and ways to enjoy apple juice without discomfort.

What is Constipation?

Constipation refers to infrequent, difficult, or incomplete bowel movements. Typically, constipation means having less than 3 bowel movements per week or stools that are hard, dry, and difficult to pass. Other symptoms of constipation include:

  • Straining during bowel movements
  • Feeling like you can’t completely empty your bowels
  • Abdominal pain or bloating
  • Small, hard stool
  • Fewer than normal bowel movements

Occasional constipation is usually nothing to worry about. However, ongoing constipation can lead to complications like hemorrhoids or bowel obstruction. Consulting a doctor is recommended if you experience persistent constipation.

Why Does Apple Juice Cause Constipation?

There are a few reasons why apple juice can contribute to or worsen constipation:

Low Fiber Content

Fiber is important for healthy bowel function. Soluble fiber soaks up water in your digestive tract to form a gel-like substance that softens and adds bulk to stool. This helps food and waste move efficiently through your system.

When juicing apples, the insoluble fiber content is removed, leaving only a small amount of soluble fiber. A 240 ml glass of apple juice contains about 0.5 grams of fiber, while a medium apple with skin provides around 4 grams of fiber.

High Fructose Content

Apples naturally contain fructose, a simple sugar. When apples are juiced, the juice concentrates the fructose, delivering a large dose of fructose in a small serving.

Too much fructose can pull water into the colon and contribute to an osmotic effect that results in loose stool or diarrhea. However, when consumed in excess over time, fructose can also have a dehydrating effect and lead to constipation.

Lack of Water

Water is important for keeping stool soft and bowel movements regular. Dehydration is a common cause of constipation.

While apple juice provides fluids, it may not be as hydrating as pure water. Drinking apple juice in place of plain water can increase your risk of inadequate hydration if intake is not balanced with other beverages.

Who is at Risk of Constipation from Apple Juice?

Apple juice doesn’t cause problems for everyone, but certain individuals are more likely to experience constipation when drinking apple juice frequently or in large amounts:

  • Toddlers and preschoolers – Apple juice is a popular beverage for little ones, but too much can lead to constipation thanks to low fiber, high sugar, and inadequate hydration. Toddler-sized digestive systems are still developing and more susceptible to the effects of excess fructose from juice.
  • Older adults – Constipation becomes more common with age thanks to slower digestion, weaker abdominal muscles, side effects of medications, and inadequate hydration. Older adults should be especially cognizant of apple juice’s low fiber and high sugar content.
  • Individuals with irritable bowel syndrome (IBS) – IBS involves bowel disturbances ranging from diarrhea to constipation. Fructose intolerance is also common with IBS. Apple juice is often poorly tolerated.
  • Those with gastrointestinal disorders – Conditions like inflammatory bowel disease (IBD) and diverticulitis increase constipation risk. The high fructose and low fiber content of apple juice can contribute to problems.
  • Anyone with fructose malabsorption – Some people don’t absorb fructose properly due to low levels of enzymes or intestinal issues. This can allow excessive fructose to make its way to the colon, resulting in diarrhea or constipation.

How Much Apple Juice Is Too Much?

There’s no universal rule for how much apple juice is too much, as individuals have different digestive tolerances. However, drinking more than about 8 ounces (240 ml) per day or 4-6 ounces (120-180 ml) per sitting could lead to excess sugar and inadequate hydration or fiber intake, especially for constipation-prone individuals.

To determine your personal tolerance, pay attention to how your body responds after drinking apple juice. Signs that you may be exceeding your limit include:

  • Increase in constipation, bloating, or gas
  • Decrease in regular bowel movements
  • Dry, hard, or painful stools
  • Incomplete evacuation
  • Hemorrhoid flare-ups
  • Increased thirst or headaches

If you experience ongoing problems after drinking apple juice, consider reducing your intake or avoiding it altogether.

Tips for Preventing Constipation from Apple Juice

You don’t necessarily have to cut apple juice out of your diet completely if you take some precautions:

  • Dilute it – Mix apple juice with equal parts water to reduce the sugar concentration and improve hydration.
  • Have it with meals – Drinking apple juice alongside foods that provide fiber can help slow absorption and improve tolerance.
  • Enjoy in moderation – Stick to 4-6 ounces maximum per sitting and 8 ounces or less per day.
  • Choose fresh apples – Eat whole apples more often since they provide fiber, nutrients, and hydration with less fructose per serving compared to juice.
  • Increase fiber – Make sure to get at least 25-30 grams of fiber from foods like vegetables, fruits, whole grains, beans, and nuts to help maintain regularity.
  • Stay hydrated – Drink plenty of water and limit caffeinated or alcoholic beverages, which can dehydrate.
  • Exercise – Physical activity stimulates the bowel and can help prevent constipation.

Paying attention to your body’s signals and making adjustments to your apple juice intake and diet can help you find the right balance. Speak to your doctor if lifestyle modifications don’t provide relief from ongoing constipation.

Other Juices That Can Cause Constipation

Apple juice isn’t the only culprit when it comes to constipation. Other juices to be mindful of include:

Juice Why It Can Cause Constipation
Orange juice Contains fructose without fiber; lower in fiber if strained vs fresh oranges
Grapefruit juice High in fructose and low in fiber; can interact with medications
Pineapple juice High sugar and low fiber content
Pear juice High in fructose, low in fiber; sorbitol content can have laxative effect in large amounts
Cranberry juice Can contain added sugar; may interact with medications
Prune juice Excess sorbitol acts as a laxative
Carrot juice Fiber lost in juicing; carrots have natural sorbitol

The key things to watch for are low fiber paired with high sugar content. While prune and pear juices contain sorbitol which acts as an osmotic laxative, overdoing any juice can tip the scales towards dehydration and constipation.

When to See a Doctor

Occasional constipation is usually not a major concern. However, if you experience any of the following, it’s a good idea to make an appointment with your doctor for evaluation:

  • Constipation lasting longer than 3 weeks
  • Blood in your stool
  • Persistent abdominal pain or vomiting
  • Unexplained weight loss
  • Bowel movements so painful they inhibit your normal activities
  • Inability to control bowel function

Your doctor can check for potential underlying causes like bowel obstruction, hemorrhoids, anal fissures, thyroid disorders, diabetes, irritable bowel syndrome, celiac disease, or colon cancer. They may order tests such as a colonoscopy or CT scan to examine your colon.

Medical Treatments for Constipation

If apple juice or other dietary factors are not behind your constipation, your doctor may recommend treatment options such as:

  • Increased fiber intake – Adding a daily fiber supplement or foods high in fiber.
  • Increased fluids – Drinking more water and limiting dehydrating beverages.
  • Osmotic laxatives – Over-the-counter products like polyethylene glycol that help draw water into the colon.
  • Stool softeners – Medications like docusate that moisten and soften stool.
  • Stimulant laxatives – Short-term use of OTC laxatives containing senna or bisacodyl.
  • Prescription laxatives – Drugs like prucalopride that promote colon motility may be prescribed for chronic constipation.
  • Enemas – Saline, mineral oil, or glycerin enemas can provide short-term relief as needed.

For immediate relief, your doctor may recommend a disimpaction procedure to manually remove built-up stool followed by maintenance therapy. Most people find relief through diet changes, fiber supplements, exercise, and OTC laxatives.

When Constipation Signals a Bigger Problem

While occasional constipation is very common, having persistently hard, dry, difficult bowel movements may be a sign of an underlying condition that needs medical attention. Contact your doctor promptly for evaluation if you experience:

  • No bowel movements for 3 or more days
  • Weakened bowel movements over several weeks or longer
  • Thin, pencil-like stools
  • Blood in stool
  • Unexplained weight loss
  • Persistent abdominal pain or cramping

These symptoms could indicate:

  • Bowel obstruction – A blockage prevents proper movement of stool. This requires immediate medical care.
  • Gastrointestinal disorders – Issues like chronic idiopathic constipation, irritable bowel syndrome, or inflammatory bowel disease may be investigated.
  • Neurological conditions – Nerve damage, spinal injury, stroke, or multiple sclerosis can impair normal colon function.
  • Metabolic disorders – Diabetes, kidney failure, or hypothyroidism are linked to motility disorders.
  • Colon cancer – While rare in younger adults, persistent changes in bowel habits warrant screening.
  • Medication side effects – Opiates, antidepressants, antacids, and other drugs can cause constipation.

Rather than chalking it up to diet, be sure to consult a doctor when significant and persistent changes in bowel habits occur.


Apple juice is a popular beverage, but drinking too much can certainly contribute to constipation in some individuals. The combination of low fiber content with a high concentration of fructose from juicing results in poor hydration and difficulties producing soft, bulky stool. Pay attention to how your body responds and limit apple juice to 8 ounces or less per day. Focus on whole foods like fruits, vegetables, whole grains, beans, nuts and seeds to get the right balance of fluid and fiber. See a doctor promptly with any persistent changes in bowel habits to rule out potential complications.
