Traditionally, colonoscopy prep involves drinking a large amount of liquids (an oral laxative formula) to help you clean out your colon. Now, there are other options that help you achieve the same ...
Levothyroxine is taken on an empty stomach about half an hour to an hour before meals. [21] As such, thyroid replacement therapy is usually taken 30 minutes prior to eating in the morning. [ 14 ] For patients with trouble taking levothyroxine in the morning, bedtime dosing is effective, as well. [ 14 ]
Thyroxine, also known as T 4, is a hormone produced by the thyroid gland.It is the primary form of thyroid hormone found in the blood and acts as a prohormone of the more active thyroid hormone, triiodothyronine (T 3). [1]
Since polyps often take 10 to 15 years to transform into cancer in someone at average risk of colorectal cancer, guidelines recommend 10 years after a normal screening colonoscopy before the next colonoscopy. (This interval does not apply to people at high risk of colorectal cancer or those who experience symptoms of the disease.) [28] [29]
Thyroid hormones act on nearly every cell in the body. They act to increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth (synergy with growth hormone) and neural maturation, and increase the body's sensitivity to catecholamines (such as adrenaline) by permissiveness.

Seriously, though: Most patietns find that drinking 4 litres by way of 250 ml glasses every ten minutes is quite difficult. Usually, the patient finds the fourth to seventh drinks to be the hardest to get down and keep down, but by then the mental powers are fully focused on finding the water closet, finding it in a hurry!
When Phospho soda is used as preparation for colonoscopy, 1.5 fluid ounces (45ml), mixed with an equal amount of water or any clear liquid and followed by 8 oz of water, is taken, followed by a second dose 6 hours later (3 oz total). It will cause very loose, eventually watery stools, usually starting within an hour or so and lasting several hours.
Blood free thyroxine and TSH levels are monitored to help determine whether the dose is adequate. This is done 4–8 weeks after the start of treatment or a change in levothyroxine dose. Once the adequate replacement dose has been established, the tests can be repeated after 6 and then 12 months, unless there is a change in symptoms. [8]
