The risk of dehydration after gastric sleeve surgery is a serious concern. You may find it difficult to drink enough water for the first few days after surgery. Identifying post-sleeve gastrectomy dehydration symptoms is critical so that you can address the problem before it leads to further complications.
In this blog, we will outline the risks of dehydration post-surgery, the early signs after gastric surgery, and some essential post-gastric sleeve hydration tips to help prevent the condition.
What are the Risks of Dehydration?
If you experience signs of dehydration after a gastric sleeve, it could lead to serious complications. You may ultimately become delirious and lose consciousness if dehydration is not addressed promptly.
Some of the more serious effects of dehydration include the following:
- Delayed recovery
- Kidney failure
- Shock
- Delirium
- Poor oral intake
Dehydration Symptoms Post Gastric Sleeve
Knowing how to tell if you are dehydrated after a gastric sleeve is an important aspect of preventing dehydration and the discomfort and complications that come with it. Dehydration can lead to delayed recovery, fatigue, and poor oral intake. This can evolve into a vicious cycle of further dehydration, further exacerbating the situation. Knowing the common dehydration signs post-bariatric surgery in early and more advanced stages is best.
Early signs of dehydration in bariatric patients include the following:
- Persistent thirst
- Dry mouth
- Fatigue
- Decreased urination
- Dark yellow urine
- Feeling dizzy or light-headed
- Cool and dry skin
Some more advanced symptoms of dehydration after weight loss surgery may include the following:
- An irregular heartbeat (Tachycardia)
- Constipation
- Low skin turgor
- Muscle cramps
If you notice any of these signs, try to drink more water. If this is difficult after your surgery, sucking on pieces of ice can help. Contact your doctor if you are unsure what to do or if your symptoms are supported.
Post-Gastric Sleeve Hydration Tips
Managing dehydration after sleeve gastrectomy is critical; the best approach is to avoid it altogether.
Here are some key tips for preventing dehydration after gastric sleeve surgery:
- Drink sufficient fluids
Hydration after gastric sleeve is extremely important. In terms of water intake you should aim for 64 to 96 ounces per day. This can include some flavored water or juice, but it is best to drink plain water most of the time.
- Drink consistently
Ensure you drink small quantities often throughout the day. Do not only drink when you are already thirsty. Drinking small amounts regularly is easier after bariatric surgery and can help prevent dehydration.
- Choose the right drinks
Carbonated and caffeinated drinks are the best way to avoid dehydration after surgery. Opt for sugar-free drinks as much as possible.
At Torrance Bariatric Institute we have implemented a post-op hydration program that includes comprehensive patient education and IV hydration supplementation in order to prevent the consequences of dehydration.
When to See a Doctor for Dehydration After Surgery
As you will likely feel out of sorts for a few days post-surgery, detecting dehydration in bariatric patients may require the eye of a medical professional. If you suspect you are experiencing signs of dehydration after a gastric sleeve, it is better to contact your doctor early on rather than wait until you have a serious issue.
If you struggle to take in enough fluids and feel constant thirst, have a dry mouth, are fatigued, have difficulty urinating, or experience dizziness or lightheadedness, it is best to call your doctor immediately.
