How Laxative Can Help You Lose Weight

Best Laxatives For Weight Loss

Studies show that 47% of women in the world use laxatives to shed extra pounds. Aside from weight loss, it also helps relieve constipation, enhance digestion, and remove excess fat and toxins from the body. But, how does it work?

Typically taken to relieve constipation, laxatives work by reacting with your gastrointestinal tract, thus regulating your bowel movement. They either soften or increase the liquid or bulk in your poo for you to pass it more quickly. Laxatives may also stimulate the muscles of your intestines or rectum to contract which helps squeeze your feces out.

Laxatives help in weight loss by increasing the amount of toxins, nutrients, fluids and fat that you excrete on your bowels. By allowing you to have a regular bowel movement, laxatives also aid in digestion and metabolism, which are crucial in maintaining your body weight.

They may also accelerate the rate or frequency of your bowel movement. This minimizes the absorption of nutrients such as protein, carbohydrates, vitamins, and minerals from your food intake.

Due to the shorter storage time of digested food in your intestines, you tend to gain fewer calories from the food that you eat. You may even pass out most of the calories even before your body has time to completely process your meal.

Hence, the danger comes once your body starts to release too much of the nutrients and calories into your poop. When what’s left does not suffice for your body’s needs, you then feel weak and tired, and health issues arise. Another is the risk of dehydration. This is why laxative use should be controlled.

Additional Benefits Of Laxatives

If you think that the only benefit that a laxative can give you is weight loss, think again! The use of laxatives can also help flush out unwanted toxins in the body, cleanse your colon, improve digestion and ultimately, stimulate your metabolism which will be beneficial in the long run.

Different Types Of Laxative

Best Laxatives For Weight Loss

Laxatives can be taken orally as capsules, tablets, or syrups. They can also be administered through the rectum as suppositories or enemas. Laxatives are categorized into four large groups according to how they work: bulk-forming, osmotic, stool softeners, and stimulant laxatives.

  • Laxatives That Form Bulk Or Fiber Supplements

As suggested by the name, they work by adding bulk to your stool. They contain indigestible, water-absorbing particles. Upon absorption of water, they tend to cause bowel accumulation. This triggers bowel movement through peristaltic movements or the alternating, wave-like contractions of intestinal wall muscles.

Bulking laxatives are plant fibers such as methylcellulose, ispaghula psyllium husk, and sterculia. A cheap kind of fiber supplement is unprocessed bran.

You cannot digest these fibers, but bacteria that are living in your intestines can. When they do, excessive intestinal gas and bloating may result.

  • Osmotic Laxatives

Osmotic laxatives are soluble yet non-absorbable compounds that draw water into your colon and your stool. This process of water transport is called osmosis. Through this action, osmotic laxatives help liquefy your feces and release it more smoothly.

  • Faecal Or Stool Softeners

Surfactants or softeners do their job by allowing fat and water to cover and saturate your stool. Some enemas and suppositories are types of stool softeners.

Usually, mineral oil mixed with juice is given as a stool lubricant to both adults and children with disabilities that limit their mobility. In hospitals, glycerin suppositories and docusate are prescribed to inpatients as a remedy for constipation.

It is also best to take note that prolonged stool softener use can cause vitamin K, D, A and E deficiencies (fat-soluble vitamins).

  • Stimulant Laxatives Or Cathartics

The method by which stimulant laxatives work is still poorly understood. However, they are known to stimulate the secretion of fluids and electrolytes in the colon and also trigger the intestinal nervous system.

Prolonged usage of this type of laxatives may cause patients dependence and intestinal nervous system damage. However, some researches contradict this. Nonetheless, prolonged use of these laxatives is only recommended for patients in hospitals or chronic rehabilitation care establishments. These include those who have a neurological impairment or are bedridden.

How To Choose A Laxative

Best Laxatives For Weight Loss

There are many different ways in choosing OTC laxatives. One good way is to consider what you need and base your next actions and decisions on them. Listed here are the things you can do or follow to help you select the best laxatives for weight loss that you need.

  • Think Of Your Desired Effect

As mentioned, laxatives can have different effects and modes of action. Once you have figured out the effect or outcome you want the laxative to have on you, it will be easier to pick the right product.

It might help to ask yourself questions like the following:

  • I have been constipated for how long?
  • Have I tried to diet, exercise, or beverages to relieve my constipation? 
  • Have I tried any other methods to relieve my constipation? 
  • Do I prefer a laxative taken orally or rectally? 
  • Do I want a stimulating laxative? 
  • For how long do I want the effects to last? 
  • Do I need to consider any special health conditions or issues?
  • Check And Review The Package Labels

Reading the package label is imperative no matter what type of laxative you may choose. Make sure that you’re getting the type or combination that you like. Watch out for contraindications or possible interactions with medications you are currently taking.

  • Consult a pharmacist or physician about your concerns regarding specific laxatives. Also, try calling the manufacturer or look for information on the company’s website or the product packaging.
  • To find out any potential risks with the laxative you’re considering, consult the Food and Drug Administration’s website about product safety, recalls, and market withdrawals.
  • Decide On Your Best Options

Narrow down your selection to a few ones that could work for you. Then compare them to make a final decision. Consider things like:

  • Product guarantees or warranty
  • Overall health 
  • Medical conditions 
  • Allergens 
  • Cost 
  • Return policies

How To Make Laxatives Become More Effective

Many people shy away from using laxatives because of the possible side effects that come with them. But the truth is, it all boils down on how you take your laxatives. When you take laxatives properly, you can be able to minimize the side effects and maximize its benefits.

The first thing that you should do is to increase your water intake in order to prevent dehydration. In addition to that, you should also consume more fruits to ensure that your body will get the nutrients it needs.

Second, you need to consult your doctor first to make sure that taking laxatives is a safe option for you and to ensure that the use of laxative won’t be interfering with any of the medications that you are currently taking if there are any.
