Type 1 and kind 2 diabetes are each outlined by excessive blood sugar ranges. Persistently excessive blood sugar can result in comparable signs and issues. However kind 1 diabetes and kind 2 diabetes are completely different ailments in lots of different methods.
About 38 million Individuals have diabetes. That’s greater than 1 out of each 10 individuals. Type 1 diabetes accounts for about 5 to 10 % of diagnoses.[1]
Right here’s what you have to know to be well being savvy within the period of a diabetes epidemic.
What Is Diabetes?
Diabetes is said to excessive blood sugar, however the kind of diabetes determines why your blood sugar stage is excessive.
What Type 1 Diabetes Does to the Physique
Folks with kind 1 diabetes don’t produce sufficient of the hormone insulin. Because of this, sugar builds up within the blood, as a substitute of going to the cells the place it’s wanted for vitality.[2] If left untreated, kind 1 diabetes is deadly. Everybody wants insulin to reside.
Folks with kind 1 diabetes self-administer insulin day by day for the remainder of their lives. Utilizing an excessive amount of or too little insulin results in each short- and long-term well being points. If kind 1 diabetes is just not managed fastidiously, it may well result in devastating penalties, akin to diabetic coma, superior kidney illness, blindness, or amputation.
What Type 2 Diabetes Does to the Physique
Type 2 diabetes begins with insulin resistance, a state by which the physique doesn’t reply correctly to the hormone insulin. Not like individuals with kind 1 diabetes, which is a illness of too little insulin, individuals with kind 2 diabetes could initially have an excessive amount of.[3]
Genetics and life-style habits each play a job within the physique’s rising insulin wants. Ultimately, the pancreas can’t produce sufficient insulin to maintain up with the demand, and blood sugar ranges go up. Because the illness progresses, the pancreas could start to lose its potential to create insulin, inflicting blood sugar ranges to rise even larger. This blood sugar rise can lead to the identical damaging penalties as in kind 1 diabetes, together with heart problems, kidney failure, and early dying.
Type 2 diabetes remedies — each medicine and life-style adjustments — are largely designed to appropriate the foundation reason behind insulin resistance, so the insulin that your physique does make works extra successfully, bringing blood sugar ranges down. If these remedies are ineffective, some sufferers will finally must self-administer insulin as a medication.
Causes
What Causes Type 1 Diabetes?
“Type 1 diabetes is an autoimmune illness. The physique’s immune system assaults the cells within the pancreas that make insulin,” says Andjela Drincic, MD, a professor within the division of diabetes, endocrinology, and metabolism on the College of Nebraska Medical Heart in Omaha.
Insulin is a important hormone that no mammal can reside with out. The sugar in your bloodstream can’t get into cells that want it for vitality with out insulin. Insulin is the important thing that unlocks a cell and permits sugar to enter.
The precise reason behind kind 1 diabetes is just not recognized, however analysis suggests it’s a mix of the genes an individual is born with and one thing within the surroundings that triggers the genes to turn into lively. Although a household historical past of kind 1 diabetes (or different autoimmune problems) can enhance the chances of growing the situation, its growth appears basically random.
What Causes Type 2 Diabetes?
“The reason behind kind 2 diabetes is multifactorial,” says Dr. Drincic. “Folks inherit genes that make them vulnerable to kind 2, however life-style components, like weight problems and inactivity, are additionally vital. In kind 2 diabetes, no less than within the early phases, there’s sufficient insulin, however the physique turns into proof against it.”
Danger components for kind 2 diabetes embrace a household historical past of the illness, poor eating regimen, sedentary life-style, and weight problems. Black, Latino, and Asian Individuals in addition to American Indians have a better threat of kind 2 diabetes than white Individuals.[4]
Diabetes at Any Age: Type 1 or Type 2
Type 1 diabetes was as soon as thought-about a childhood illness; it was even known as juvenile diabetes beforehand, however that’s not the case right this moment. Although the situation is frequent in youth, specialists now acknowledge that greater than half of latest circumstances are identified in individuals age 18 and older.[5]
The onset of kind 1 diabetes could also be extra gradual in adults than in youngsters. Some adults have a subtype of kind 1 diabetes known as LADA (latent autoimmune diabetes in adults), which progresses particularly slowly. This implies kind 2 medicines could appear efficient for a number of years earlier than insulin remedy is critical.
Due to its slower onset, kind 1 diabetes is commonly misdiagnosed as kind 2 diabetes in adults. Roughly 38 % of adults with kind 1 are initially misdiagnosed with kind 2.[6]
Type 2 diabetes is usually thought-about a illness of older adults, as the danger will increase with age.[7] However that doesn’t imply that the situation can’t happen at earlier ages. Immediately, extra youngsters are being identified with kind 2 diabetes.[8] When it develops at an earlier age, kind 2 diabetes is related to extra extreme well being outcomes.[9]
Signs
The Signs of Type 1 Diabetes
Most often, the primary signs of kind 1 diabetes seem solely after blood sugar ranges have elevated to a dangerously excessive stage.
These signs embrace elevated thirst, frequent urination, unexplained weight reduction, and blurred imaginative and prescient. Folks might also expertise speedy respiration, dry pores and skin, fruity breath, and nausea.
In extreme circumstances, undiagnosed kind 1 diabetes can result in a situation named diabetic ketoacidosis (DKA). DKA is life-threatening and needs to be handled in an emergency room with intravenous fluids and insulin. Many individuals with kind 1 diabetes are identified solely after growing DKA. For those who suspect you’re in DKA, get quick remedy.
The Signs of Type 2 Diabetes

This implies the illness can quietly harm nerves and blood vessels all through the physique for years.
Many individuals with kind 2 diabetes are identified at routine checkups, earlier than they expertise any signs. Others could discover a number of of the numerous refined signs of chronically elevated blood sugar ranges, together with fatigue, dry mouth, infected gums, erectile dysfunction, recurring yeast infections, numbness or tingling within the extremities, and gradual wound therapeutic.
If left untreated, kind 2 diabetes can result in the identical signs of acute excessive blood sugar as kind 1 diabetes, akin to frequent urination, thirst, starvation, blurred imaginative and prescient, and unexplained weight reduction. In uncommon conditions, individuals with kind 2 diabetes may also develop DKA.[10]
Diagnosing Varieties 1 and a pair of Diabetes
Each types of diabetes, that are every outlined by excessive blood sugar ranges, are identified utilizing the identical exams. Blood exams to diagnose kind 1 and kind 2 diabetes embrace fasting blood sugar, a hemoglobin A1C take a look at, and a glucose tolerance take a look at.[11] The A1C take a look at measures the typical blood sugar stage over the previous few months. The glucose tolerance take a look at measures blood sugar after a sugary drink is given.
“The blood sugar testing we do to diagnose and handle kind 1 diabetes is similar to the testing we do for kind 2 diabetes,” Drincic says. “We are able to do a blood take a look at that appears for antibodies. That tells us whether it is kind 1 or 2.”
Figuring out a kind 1 versus kind 2 diabetes prognosis can embrace the next:
- Testing for Autoantibodies Autoantibodies develop when the immune system assaults the cells within the pancreas that produce insulin. The presence of autoantibodies signifies kind 1 diabetes. Your healthcare supplier can prepare a blood draw for an autoantibody screening, however there are additionally a number of sources to get screened at dwelling. A nonprofit named The Diabetes Hyperlink curates an inventory of choices for at-home screening.
- C-Peptide Ranges C-peptide signifies how a lot insulin your pancreas is producing. Folks with kind 1 diabetes have very low c-peptide ranges, whereas individuals with kind 2 are inclined to have very excessive c-peptide ranges. C-peptide ranges are examined by way of a conventional intravenous blood draw.[12]
Your physician could suspect kind 2 diabetes based mostly on threat components akin to weight problems and household historical past, or signs akin to darkish, velvety pores and skin (acanthosis nigricans). Contemplating the speed of misdiagnosis, it might be prudent to rule out kind 1 diabetes no matter your weight or age by testing your c-peptide stage or checking for autoantibodies.
The Remedy of Type 1 and Type 2 Diabetes
Treating and managing kind 1 or kind 2 diabetes can contain a number of life-style behavior adjustments, medicines, and know-how, and there’s a substantial amount of overlap between the 2 situations.

Insulin is probably a very powerful drug within the remedy of diabetes. “The large distinction is that everyone with kind 1 diabetes must take insulin,” says Shannon Knapp, RN, CDCES, a diabetes educator on the Cleveland Clinic in Ohio.
Folks with kind 1 diabetes have an absolute want for the hormone insulin and can finally die with out it. Most individuals with the situation must take insulin a number of instances day by day, typically deciding themselves how a lot insulin to take and when. Insulin lowers blood sugar ranges powerfully, however it may well set off the harmful aspect impact of hypoglycemia. There’s a substantial studying curve to using this drug.
Immediately’s insulin choices are huge, and so are the applied sciences you need to use to dose and administer insulin. Insulin is available in a number of varieties. It may be administered by injection or infused repeatedly with an insulin pump. Inhaled insulin can also be accessible. Some newer insulin pumps provide a hybrid closed-loop system that communicates immediately with a steady glucose monitor, making computerized changes to insulin doses.
Medicine for Type 2 Diabetes
There isn’t any one-size-fits-all strategy to kind 2 diabetes medicines. Although most individuals with kind 2 diabetes are provided metformin as a first-line remedy, your healthcare supplier will contemplate your total well being profile in recommending further drug therapies.
Different choices embrace:
These medicines work in numerous methods to enhance blood sugar ranges or insulin resistance. The latest drug lessons, GLP-1 receptor agonists and SGLT2 inhibitors, additionally provide long-term safety to kidney and coronary heart well being.
Everybody reacts otherwise to those medicines, which implies you need to inform your physician instantly for those who’re experiencing extreme unwanted side effects or for those who aren’t seeing enhancements in your blood sugar ranges.
Whereas the above medicines are accredited by the U.S. Meals and Drug Administration solely to deal with kind 2 diabetes, some are additionally prescribed off-label to individuals with kind 1 diabetes.

Lastly, insulin is an possibility for individuals with kind 2 diabetes who’ve been unable to maintain their blood sugar at a protected stage with the opposite medication and life-style adjustments. “Over time, if the pancreas stops making insulin, some individuals with kind 2 may also want insulin,” says Knapp.
Blood Sugar Monitoring
Monitoring your blood sugar ranges is important in each kind 1 and kind 2 diabetes. The extra conscious you might be of your blood glucose, the simpler it’s to know what adjustments in eating regimen, train, life-style, or medicine will profit your metabolic well being.
When they’re first identified, most individuals with diabetes are given a prescription for a blood glucose meter. These units measure blood sugar ranges from a drop of blood; the measurements are typically known as finger sticks as a result of the units use a pointy lancet to attract blood from the fingertips.
A more recent know-how, the continual glucose monitor (CGM) can measure blood sugar ranges across the clock. This system adheres to the higher arm, torso, or elsewhere on the physique. A small hairlike cannula penetrates beneath the pores and skin. The CGM routinely updates a smartphone app or devoted CGM transmitter with new measurements. It may additionally increase an alarm if blood sugar ranges are trending dangerously excessive or low.
All individuals with diabetes who use insulin are inspired to test blood sugar ranges a number of instances per day and might profit particularly from using CGMs. Insurers could also be much less wanting to cowl the price of a CGM for individuals with kind 2 diabetes who don’t require insulin with each meal, however the system can nonetheless assist decrease A1C ranges, and it’s getting simpler to purchase a CGM over-the-counter.[16]
What Are the Issues of Diabetes?
The issues of diabetes — long-term well being situations which are partially or totally brought on by diabetes — are largely the results of persistently excessive blood sugar ranges. Extra sugar in your bloodstream wreaks havoc on blood vessels and nerves all through your total physique.
“Whether or not it’s kind 1 or kind 2,” Drinsic says, “the large image for diabetes is all about stopping issues,” that are largely associated to nerve and blood vessel harm.
Diabetes impacts virtually each a part of the physique. A partial record of issues contains:
These situations can progress to extreme states, particularly if diabetes is left unmanaged for a very long time. A few of the worst outcomes of diabetes embrace amputation, blindness, and early dying. Folks with kind 1 and kind 2 diabetes are each liable to these dire penalties.
To reduce or forestall diabetes issues, the American Diabetes Affiliation units a purpose for many adults of an A1C beneath 7.0 %.[17]
Prevention
Can Type 1 Diabetes be Prevented?
“As of now, there isn’t any method to forestall kind 1 diabetes,” Drincic says. A major variety of scientific trials are ongoing, with the purpose of stopping or delaying the situation, and one drug is accredited to delay the onset of full-blown kind 1 diabetes, based on On a regular basis Well being’s community web site Diabetes Every day.
Can Type 2 Diabetes be Prevented?
It takes effort, however kind 2 diabetes could be prevented earlier than it develops.
“One of the best treatment for kind 2 diabetes is prevention, and analysis on that may be very thrilling,” Drincic says. “Shedding a reasonable quantity of weight and exercising repeatedly can scale back or delay kind 2 diabetes considerably.”
A landmark Finnish research adopted 522 middle-aged adults who have been obese and had threat components for kind 2 diabetes. A weight-loss eating regimen and half-hour of day by day train lowered their threat of growing kind 2 diabetes by 58 % in contrast with those that didn’t comply with the eating regimen or train.[18]
Diabetes Cures and Remission
There isn’t any treatment for kind 1 diabetes, however the analysis right into a potential treatment seems to be extraordinarily promising. Some individuals with kind 1 diabetes have been cured of the necessity for day by day insulin injections with transplants of the pancreas or pancreatic cells, however these options, which depend on organ donors and require vital regimens of immunosuppressive medication, are impractical or inaccessible for most individuals with the illness.[19] It’s doable that within the coming many years, there shall be a workable kind 1 diabetes treatment.
Type 2 diabetes can’t be cured precisely, however it’s doable to place the illness into remission.[20] Some individuals — particularly those that have been not too long ago identified with kind 2 diabetes — can obtain regular blood sugar ranges completely by way of adjustments in eating regimen, train, and weight reduction.[21]
Others will all the time want medication to assist maintain their blood sugar ranges below management, regardless of how fastidiously they comply with eating regimen and train suggestions. Type 2 diabetes is taken into account a progressive illness. Since your pure potential to provide insulin regularly declines or insulin resistance worsens, you could finally want stronger medicines, akin to GLP-1s or insulin, to handle your situation.[22]
