Stephen Orr (Orr) filed a law suit against Wal-Mart Stores, Inc. (Wal-Mart) alleging violations of the Americans with Disabilities Act (ADA) and the Nebraska Fair Employment Practices Act (NFEPA). Concluding Orr failed to show he was disabled under either the ADA or the NFE-PA, the district court1 granted summary judgment in favor of Wal-Mart. Orr appeals. We affirm.
I. BACKGROUND
Stephen Orr is a pharmacist licensed in Nebraska, Wyoming, and South Dakota. In 1986, Orr was diagnosed with diabetes. To control his diabetes, Orr uses a glucom-eter to monitor his blood glucose levels, takes insulin, and eats a special diet within thirty minutes of taking insulin. During the time relevant to this lawsuit, Orr injected insulin three times each day — in early morning, at noon, and before bedtime. Orr controls his disease to the best of his ability. When his diabetes is not well controlled, he suffers from vision impairment, low energy, lack of concentration and mental awareness, lack of physical strength and coordination, slurred speech, difficulties typing and reading, and slowed performance.
In January 1998, Orr became employed full time as a pharmacist at a Wal-Mart store in Chadron, Nebraska. This Cha-dron store was a single-pharmacist Wal-Mart facility, and Orr was the only pharmacist on duty during his work day. Before accepting employment, Orr informed Wal-Mart District Manager Rick Coleman (Coleman) he was an insulin-dependent diabetic. Coleman authorized Orr to take a lunch break and mid-day breaks during his ten-hour work shift. Orr understood Coleman to authorize him to take an uninterrupted lunch break, and Orr routinely closed the pharmacy for thirty minutes over the noon hour to eat lunch.
John Foss (Foss) succeeded Coleman as district manager in charge of the Chadron store. Foss informed Orr that Wal-Mart policy2 required the pharmacy to remain open during store hours and instructed Orr not to close the pharmacy during his lunch break. Orr did not comply with Wal-Mart policy and continued to close .the pharmacy for thirty minutes in order to take an uninterrupted lunch. On March 5, 1998, Foss issued Orr a written warning for closing the pharmacy. The written warning stated that further non-compliance would result in Orr’s termination.
Orr responded in writing to the warning with his “action plan” and without mentioning his diabetes.
Per this presentation & our discussion of the issues a[t] hand. I respectfully protest this presentation & Decision-Making Day. My understanding of time off for lunch & breaks apparently was a misunderstanding of company policy as presented by Rick Coleman. My leaving the Pharmacy on 2/25 was specifically for company (Pharmacy) business to pick up a CII Rx at the Clinic.
*723I will from this date forward take my lunch break within the confines of the Pharmacy & maintain the opening of the Pharmacy from 9-7 AM Mon.-Fri & 9-6 on Sat during my scheduled days shift.
Orr initially abided by Wal-Mart’s policy and kept the pharmacy continuously open during store hours. However, a week after receiving the written warning, Orr wrote to Foss requesting he rescind the written warning based on Orr’s original understanding and agreement with Coleman. Orr stated, in part: “I had discussed with Rick Coleman during the interview process conducted at Wal-Mart in Rapid City, that I was an Insulin Dependent Diabetic. Rick Coleman agreed that I could take lunch breaks.” On April 8, 1998, after receiving no response, Orr wrote to Foss again asking him to remove the written warning from Orr’s personnel file. In his second letter, Orr informed Foss that, due to his adherence to Wal-Mart policy requiring the pharmacy to remain open, he was unable to eat until “much after noon, resulting in my experiencing symptoms of hypoglycemia.” Orr expressed concern that not having an uninterrupted lunch break could adversely affect the control of his diabetes.
On April 17,1998, Foss wrote to Orr and advised him that the written warning would not be rescinded. Foss said he had discussed the situation with higher management. Foss’s letter informed Orr that Coleman denied ever authorizing Orr to close the pharmacy to take a lunch break. In his letter Foss also explained that Wal-Mart had always permitted Orr to control his diabetes by bringing food into the pharmacy, providing access to a refrigerator, and allowing him to eat or snack in the pharmacy.
On April 24, 1998, Orr wrote Foss and again asked him to rescind the written warning. Orr’s letter relayed to Foss that working in the pharmacy without an uninterrupted daily lunch break was adversely affecting the control of his diabetes. On May 7, 1998, Orr wrote another letter to Foss, informing him that, as a result of the no lunch break policy, Orr had incurred “several low, hypoglycemic incidents.” Orr expressed his disappointment with Wal-Mart’s indifference to his needs as a diabetic, and Orr informed Foss he was resuming noon lunch breaks away from the pharmacy for the maintenance of his diabetic health. Thereafter, Foss terminated Orr.
II. DISCUSSION
Orr argues the district court erred in finding he was , not disabled, within the meaning of the ADA. Under the ADA, a disability is defined as “a physical or mental impairment that substantially limits one or more of the major life activities of such individual.” 42 U.S.C. § 12102(2)(A).
The disability discrimination provisions in the NFEPA are patterned after the ADA, and the statutory definitions of “disability” and “qualified individual with a disability” contained in the NFEPA are virtually identical to the definitions of the ADA. See Neb.Rev.Stat.Ann. § 48-1102(9) & (10); 42 U.S.C. §§ 12102(2), 12111(8). In construing the NFEPA, Nebraska courts have looked to federal decisions, because the NFEPA is patterned after Title VII and the ADA. See, e.g., Father Flanagan’s Boys’ Home v. Agnew, 256 Neb. 394, 590 N.W.2d 688, 693 (1999); IBP, Inc. v. Sands, 252 Neb. 573, 563 N.W.2d 353, 357-59 (1997). We therefore employ the same analysis to determine whether Orr’s diabetes constitutes a disability under both the ADA and the NFEPA.
In Sutton v. United Air Lines, Inc., 527 U.S. 471, 483, 119 S.Ct. 2139, 144 L.Ed.2d 450 (1999), the Supreme Court held that *724the threshold inquiry whether an individual is disabled is analyzed on an individualized basis. The Court concluded that a diabetic is not per se disabled but must demonstrate his condition substantially limits one or more major life activities. Id. at 482-83, 119 S.Ct. 2139. The Court emphasized that “[a] person whose physical or mental impairment is corrected by medication or other measures does not have an impairment that presently ‘substantially limits’ a major life activity.” Id. at 482-83, 119 S.Ct. 2139.
Orr claims his diabetes substantially affects his ability to see, speak, type, read, and walk. Orr also argues “it would not be unreasonable to expect that [his] diabetic condition will significantly disrupt his lifestyle.” (emphasis added). Orr also contends that if he fails to properly monitor and treat his diabetes, then he “could experience” adverse symptoms which “would ... substantially limit [his] major life activity of working.” (emphasis added).
The Supreme Court in Sutton expressly ruled that “[a] ‘disability’ exists only where an impairment ‘substantially limits’ a major life activity, not where it ‘might,’ ‘could,’ or ‘would’ be substantially limiting if mitigating measures were not taken.” Sutton, 527 U.S. at 482, 119 S.Ct. 2139 (emphasis added). Therefore, neither the district court nor we can consider what would or could occur if Orr failed to treat his diabetes or how his diabetes might develop in the future. Rather, Sutton requires that we examine Orr’s present condition with reference to the mitigating measures taken, i.e., insulin injections and diet, and the actual consequences which followed. Seé id.
In resisting summary judgment, Orr failed to present evidence explaining either how diabetes substantially affects his major life activities or the duration and frequency of any limitations-. “[M]ost disabilities from which people suffer,” including diabetes, “do not have a substantial enough effect on their major life activities.” Berg v. Norand Corp., 169 F.3d 1140, 1145 (8th Cir.1999) (quoting Dalton v. Subaru-Isuzu Auto., Inc., 141 F.3d 667, 675 (7th Cir.1998)). Health conditions that cause moderate limitations on major life activities do not constitute disabilities under the ADA. See Taylor v. Nimock’s Oil Co., 214 F.3d 957, 960 (8th Cir.2000) (heart disease); Weber v. Strippit, Inc., 186 F.3d 907, 914 (8th Cir.1999) (heart disease). To hold otherwise could expand the ADA to recognize almost every working American as disabled to some degree.
Our review of the record establishes that Orr does not have an actual disability which presently and substantially limits a major life activity. He, therefore, is not disabled under the ADA or the NFEPA.
On appeal, Orr argues eating is a major life activity that is substantially limited due to his diabetes, and the necessity of adhering to a strict dietary regimen substantially limits the major life activity of working.3 He urges this panel to adopt the holding of a recent Seventh Circuit case that, in the context of insulin-dependent diabetes, eating constitutes a major *725life activity. See Lawson v. CSX Transp., Inc., 245 F.3d 916, 923 (7th Cir.2001).4 Orr did not allege in his complaint or argue in the district court that eating is a major life activity which is substantially limited because of his diabetes.5 Ordinarily, we do not consider an argument raised for the first time on appeal. See Shelton v. ContiGroup Cos., 285 F.3d 640, 643 (8th Cir.2002); Berg, 169 F.3d at 1145. We consider a newly raised argument only if it is purely legal and requires no additional factual development, or if a manifest injustice would otherwise result. Orion Fin. Corp. of S.D. v. Amer. Foods Group, Inc., 281 F.3d 733, 740 (8th Cir.2002). Orr does not persuade us that either exception applies. We therefore decline to consider the argument on appeal.6
III. CONCLUSION
For the reasons cited above, we affirm the judgment of the district court.
. The Honorable Lyle E. Strom, United States District Judge for the District of Nebraska.
. The applicable part of the Wal-Mart Breaks/ Lunch Period policy stated:
In pharmacies with one pharmacist on duty, the pharmacist cannot leave the pharmacy area unsupervised for any regular length of time for breaks or lunch periods. Therefore, the pharmacist will take time between busy periods for a break or eating lunch in the pharmacy prescription area,
(emphasis in original).
. In Sutton, the Supreme Court assumed working is a major life activity, but questioned whether it is, noting the EEOC’s reluctance to define "major life activities” to include working and its suggestion that working be considered a "residual life activity.” Sutton, 527 U.S. at 492, 119 S.Ct. 2139 (citing 29 C.F.R. pt. 1630, App. § 1630.20 (1998)). More recently, the Supreme Court expressed skepticism as to whether working can be a major life activity, but did not decide the issue. Toyota Motor Mfg., Ky., Inc. v. Williams, 534 U.S. 184, —, 122 S.Ct. 681, 692, 151 L.Ed.2d 615 (2002) ("Because of the conceptual difficulties inherent in the argument that working could be a major life activity, we have been hesitant to hold as much, and we need not decide this difficult question *725today.”). In this circuit we have followed Sutton and Toyota in assuming, without conclusively ruling, that working constitutes a major life activity for purposes of applying the ADA. See Duty v. Norton-Alcoa Proppants, 293 F.3d 481, 491 n. 3 (8th Cir.2002); Kellogg v. Union Pacific R.R., 233 F.3d 1083, 1087 (8th Cir.2000).
. We note Lawson was first cited by the district court in a footnote within its Memorandum and Order granting summary judgment.
. Had Orr established a prima facie case of actual disability under the ADA, Wal-Mart could have raised the threat-to-self defense. Wal-Mart could have argued that, accepting Orr's contentions at face value, working in a single-pharmacist pharmacy, which did not provide for uninterrupted meal breaks, posed a direct threat to Orr's health and that Wal-Mart was justified in not continuing his employment. See Chevron U.S.A. Inc. v. Echazabal, — U.S. —, 122 S.Ct. 2045, 153 L.Ed.2d 82 (2002).
. Even if the limitations on Orr’s ability to eat can be tied to his ability to work, they cannot salvage his claim under the ADA. "When the major life activity under consideration is that of working, the statutory phrase 'substantially limits' requires, at a minimum, that plaintiffs allege they are unable to work in a broad range of jobs.” Sutton, 527 U.S. at 491, 119 S.Ct. 2139. See also 29 C.F.R pt. 1630.2(j)(3)(i), App. § 1630.2(j) (2000). The record reveals only that Orr's diabetic condition occasionally produced symptoms which moderately impaired his performance as a pharmacist in a single-pharmacist-on-duty retail store. In contrast to the diabetic plaintiff in Lawson, Orr consistently performed the essential functions of a pharmacist before, during, and after his employment with Wal-Mart. Because Orr's diabetes, as portrayed by the record in this case, at most, only moderately limits his ability to perform a particular specialized job or a narrow range of retail pharmacist jobs, his diabetic condition does not place substantial limitations on his ability to work.
